Rectoverbs and Tremoverbs are some very versatile amps. If you like the tone, you really can't go wrong with them. They are very easy to dial in and have nice clean tones too.
:lol: On the other hand, I sold my Rectoverb and bought a DC-3.
I would suggest the following based on your budget:
DC-10 2x12 combo - great amps with Fender like cleans, seriously sick distortion and a footswitchable EQ that can be used to get that canned Metal tone or ....I use it for a Lead boost. When I play out with this amp, I get some serious compliments on my tones.
It's heavier than a dead priest though.
DC-3 1x12 combo - A friend of mine has my 1st DC-3. He plays Death Metal on it. Great all around amp that is cheap and light.
Here are some of his tones: http://www.myspace.com/sadistmotherfolkart
Rectoverb 1x12 combo - I used it for Metal and Classic Rock with no problems at all. Extremely versatile if you know how to dial amps in.
Use it with JJ E34L's and you will get some very nice British tones out of it.
Any of these 3 amps will get the job done nicely for well under your budget range. A DC-10 is a bit harder to find, but so far, it is my favorite Mesa amp.
