The newer Ampeg stuff is a pretty good buy. They actually sell parts for them and I think Loud technologies is now the parent co.
The little bass mate combos that Mike showed are really great for home use. They're killer little guitar amps too, and of course all tube. At my place I use an old Fender bandmaster @ 30 watts with a single 15. Works great for jams and recording.
Buying used will get you the very best deal. I'd imagine Vegas has lots of outlets for used music gear. Pawn shops, alleys and casinos parking lots come to mind.
