Long response, but imo the most for the money (qc/features) are:
Edit: (recommend looking at features, lots have stainless, different woods, electronics, etc... too much to list for one post)
Soapbar pickups models have way more options due to different manufacture's takes on degrees with their pickups on non soapbar models. You may get stuck and no options for replacements without swapping/modding baseplates otherwise)
Thin necks (think wizard)
2019-2023 Legator N8FP, G8FP, SP8F (used can often be found cheap) My personal favorite necks. 2024 are hit or miss on QC. Easy to identify by ebony fingerboards and the first numbers on the serial for year. Made at World Music Korea, would personally call this era for WMI the new MIJ 1980's for QC/Most for money.
2024 Legator N8FSS or G8FSS (Stainless frets, richlite, active electronics comes in beautiful purple
)
NOT the models with FS at the end only FSS.
FS = MIC and feel like a toy often GC will mark as a FP model, but if it has a maple board it's chinese FS. FSS made in Indonesia.
2023+ Ibanez RGDMS8 (can be found used for under $1k) Name is about the only thing it has over Legator, comes only in primer gray and gold hardware.
Thick(er) Necks (more round/chunky)
2016+ Agile models with the word Nirvana, mod, or pro in the model name. Probably the best extended range guitars for the money, may need a setup if bought new, take that into consideration if you don't diy. They will often have blems or leftover models on sale at Rondomusic for decent discounts. Click "Summer sale" on main page. The Nirvana models and Pendelum pro are probably the best values, imo, but may have features you/he doesn't want.
2017+ Jackson SLAT8FF also known as Jackson SLAT8X depending on year. Great overall, best value for name brand, imo. Only comes in black, though there is a SLATX8Q model that comes with a trans-black quilt finish, but harder to find replacement pickups.
Schecter PT-8 MS (New model tele) New is a bit higher than your budget, but few other tele variants in 8 string. Only has bridge pickup.
Any Ormsby, have to go used to meet budget, best roll of the dice QC, but generally more expensive.
Tremelo Models
2021-22 Dean Exile or ML select models are one of the few that come with a tremelo, kahlers in this case. New at close to $3k, every once in a while I've seen used pop up for at or under $1k. Kind of ugly finish, but awesome overall. One of my favorites and very odd multiscale leaning towards shredding as it makes for very awkward chords.
2024 Agile Perihelion or SS8TM
2016+ Agile Pendelum, Spector, Intercepor Elite models

If sticking with equal scale, I would say that the new Legator N8SS or G8SS models are the overall best value, imo. Some name brands like Ibanez, Jackson, Schecter, etc.. all have models in the $600-800 range (new), but imo the above are all more for the money using better woods, finishes, often better electronics, and have lower hours between tool resetting times (higher chance of tight tolerances vs most name brands in the sub $1k). That's not to say there aren't good models with name brands, but you'll have to go used to get an equal instrument and will still be more $ if comparing used to the above, usually. I would say the (new price) $700-1k models from Legator or Agile are in the same realm as the often $1,300-2k models from Ibanez, Schecter or Jackson. If you can find the latter for your price, by all means.
It seems that most any from WMI or Cort in the last 5 years (sans some 2024s) are going to be good/on par with one another despite the brand on the headstock. Fanned frets are awesome for tension, intonation, and comfort. Some models will come in more than one offering of scale lengths (mainly Agiles) which translates mainly into it's comfort for tuning/string gauge, etc...
I'm not against equal scale, but there are benefits to the multiscales that are better for the long term, imo/ime. The closer the two scales are to each other the better for chords. I would recommend researching the neutral/parallel/zero fret to help decide, but basically I recommend finding one where it's within the most often used area of the fingerboard for the specific individual needs for speed and comfort. If it's a surprise gift I would say Legator or Agile you can't go wrong. A bonus is that most of these can be found used for much less than new and in great condition because people tend to give up on them quickly. Whichever direction you go, unless you come across an amazing deal too good to pass I would expect this year to have really good black friday deals. A lot of these are also at certain sellers on reverb marked as used mint, but are actually new (to undermine MAP, imo).
There's a whole rabbit hole to go down, but focus on scale lengths (closer each side is in length=easier chords, further = better string tension balance and intonation) and where the parallel fret is located for the player otherwise it might be uncomfortable for use as a single option. One of the reasons of I have so many of them. Different tunings, tones and whether good for lead or rhythm and where on the fingerboard those are played. Parallel fret at the 7-9 ar probably most versatile, the farther down (say 10-12th fret parallel) will make for harder cowboy chords, but better 12+ shredding.
TL;DR? Equal length or Parallel Fret on multiscales at or around the 8th for most versatile instrument. World Korea or Cort Indonesia, 2019+
