To be honest, it's kind of difficult to say what kind of amp you should get without knowing the rest of your set up, what kind of sound you're looking for etc.
I use Ashdown amps, and love 'em, but that doesn't mean everyone will. On a limited budget, I'd be checking out the Ashdown MAG range, the SWR Workingman's stuff, the new Euphonic amps, and maybe Trace or Hartke...
I've not liked the Crate stuff that I've tried, but there are plenty of people who do like it, so I guess that counts for something...
good luck in your search for the right sound... :o)
