Keeping with your specific requirements it sounds like you should check out the Gallien Krueger MB series.
Probably on the high end of but certiainly within your budget - 210 and 212 models available.
Even a 410 combo if that's your thing!
No compression but on board limiters.
And lightweight. http://www.musiciansfriend.com/ampli...bass-combo-amp
For more budget friendly options yet perfectly giggable (is that a word?) combos in general I like Ampeg's BA series and Peavey's Max series combos and would encourage anyone to check them out for smaller venue work.
Clubs: LGBT #39, Blues Bassist #5, Official Fender Precision #95, Acoustic Bass Fetish #100, Peavey Amps #50, Ampeg Fam' Reunion #1004, Virginia Bassist #127, Reggae Bassist club
