well.. i'm certainly not a fan of the cs2x, so i'd go with the jx305 over the latter.. however, i would seriously recommend rolands jp8000. It's along the same lines as jx305 and it's pretty powerful as far as i'm concerned and there is so much you can do with it. I love mine to death, and i've seen them used for around $900.. that's comparable to the jx isn't it?? i'm not sure.
