I like the timeworks reverb 4080L (software), theres not many parameters but it sounds good on certain sounds. I use it on my kickdrums and then compress it. Great for those offbeat acid techno reverbs. I wouldnt spend loads of money on a bad ass reverb unit. Esp if you dirty your sounds up. Something like a cheap zoom studio 1201 and some eq would probably do the trick. Also the new ultra funk R3 reverb sounds good.
