Definately grab them. I use mine to totally crush the drum submix for parallel compression, and it sounds awesome. The gate feature I've found to be sorta useless, but the comp is more than great. IMO its not that great on program that is more of a constant level (distorted guitars, stereo mix, etc...), but material that is very dynamic will work well with this comp.
Got mine for $70, and it was well worth that price.
