hello i'm looking into a few synths a nd kurzweil happens to be one of them. i was looking at the 2600r and then i saw the k2661. i am really just looking for rack synths not keyboards.i also am lokking for a korg ms2000r and then i saw the ms2000br.which one is better. i also am looking into waldorf the q rack 32 voice.and a roland jp8080. if anyone can help me out by explaining the comparisons between the kurzweil's and the korgs that would be great. any other opinions on the others would be great. also any suugestions on vintage analog or good sounding synths would be much appreciated.
