What kind of amp(s) would suit these guitars?

I'm interested in a little feedback from fellow musicians on yahoo. I have several different guitars and I'm curious what would be the best sounding amp for all the guitars I have. My main guitar is a Schecter Omen-6, Schecter C1FR, a Zakk Wylde Epiphone, Fender 60's Strat, Fender Frankenstrat (a guitar I built myself), Ibanez S7320 (Seven string), and Gibson Les Paul Standard. The two new amps I've been looking at are either a Peavey 6505 or 6505+ or a JCM800. Does anyone have any suggestions for amps that would be fitting for all the guitars I play?
