I got a Drumtraks for $150 a coupla months ago but with a broken metronome out knob.
I love it. It has quenched my thirst for a DMX or Linn for now and the one I bought had all 99 memories full of awesome hiphop, funk and disco rhythms. You could tell there were different parts of about ten songs and then about 40-50 wonderful solo rhythms.
I bought some KRK 8s (the cheaper ones) at a pawn shop today for $150 Canadian and thought I'd struck gold in my cheap monitor quest but one of them doesn't make sound at all. No thump, no noise, nothing. It powers up but no sound. I did every concievable test. Too bad, because the other one is fine and they're in decent cosmetic shape. The crossover switch sticks as the lady at the pawn shop put it. Well, it sticks because it's probably broken off from the inside and can't find a setting at all.
I could get somebody to look at it but I bought them on the condition that I could bring them back if they don't work so I'm just going to do that.
I'm still trying to decide whether I want to buy powered monitors in the $500-$600 range (Yorkvilles, cheap KRK 8s, M-Audios) or spend the same amount on an audiophile brand of bookshelves and power it with an amp that's probably better than what's inside those budget monitors. And later add a sub if need be.
Powered are just so convenient. And I do like me some convenience.
