I was in the same boat, and eventually settled on
a Vox Cambridge 30. You would probably have to get one used because Korg discontinued them about two years ago, but they are around $200.00 if you find a reasonable seller. Heck, that's what I paid for a new one. They aren't the loudest thing, but if you push them they might be able to keep up with a drummer. I haven't tried the twin; it's also a 30-watter but has two tens.
Another amp that I tried and liked (and, if it hadn't have been for the deal I got on a new Cambridge, would have bought) was
the Hughes and Kettner Edition Blue 30. It's only a 1-10 combo, like the Cambridge, but has a closed-back cab, a nice CD input, pretty good tone, nice gain, and a cool light up knob panel. I think that they are about $210.00 new. Check one out...I think you might be impressed.
Oh, well. That's my two cents.
