Just picked up a used EH Holy Grail for my Rebel a coupla weeks ago. Sounds great, simple, single knob, 3 verbs. I use the spring mostly but the Hall and Flerb are definitely useable as well. I've run it through the loop and in front, sounds great either way. There's the HG+ also if you want more flexibility/knobs but it's a little more $. I think the price might be coming down too because EH started using the smaller diecast (MXR style) enclosures but I haven't been able to find them online yet for price. Hope this helps.
