you could try the vox ad120... thats what i've got and have been extremely happy with it. if you wanted the same thing but bigger get the VTH head and cab.
as you've got a lot more money to spend than i did, you might want to consider the AC30 which is one of the best amps for classic rock IMHO.

otherwise just go to a good guitar shop and try everything out. thats always the best way! :D
