Gemini Have brought somthing similar out called fx7000 ( I think ?), We sell them where I work, took it home just the other night to compare againts my tascam, obviously the tascam was better by a long way but the gemini had some very good effects for the money ( £249 ). You could munipulate the effects quite alot & it also has a wet & dry knob ( sounds good

) which allows you to adjust the filter or effect whilst in the mix.
Gemini stuff aint bad for the money but if you want proper quality you need to be spending £500 plus for a Pioneer, Allen & Heath, tascam ect.
Behringer stuff is a bit ropey, I had a composer pro compressor which was well noisey, hissing & crackling all the time in the background. I havent heard a good word about them myself, sounds like other people dont get on with them either !
