I'd associate Ben Fargen more with improved takes on Fender tweed and blackface designs than Marshalls, but he's put out great amps based on Vox and Marshall designs too.
I've had a variety of his Marshall-inspired amps: his first version (MKI) of the Mini-Plex (switchable 8/12 watts) & Mighty-Plex (40 watts) as well as a MKII Mini-Plex (redesign with MM trannies, powerscaling, and more gain), an Olde 800 (50 watt, JCM800-based) and a 25 watt version of the Olde 800.
Great amps and customer service is second to none. I'd say his amps lean more towards vintage Marshalls with improved features than modded, revoiced Marshalls like Friedman. Seems like he's been upping the gain on his amps in recent years, though. Kinda OT, but I'm not sure I've ever seen him release a Marshall-style amp with more than 50 watts.
IMO, Fargen's forte is getting classic Marshall sounds, with some modern features, at lower volumes.
The only thing I have negative to say is that resale value can be rough, but I guess that's the case for lots of boutique amps. I think they don't get more press because they're a small company and the market is somewhat saturated. They'd definitely be worthy of attention, though.
