A K2500 rackmount is definetly worth getting. Price has always been an issue with me, it seems that Kurzes products are up there, but their power, flexability and expandability make them some of the most powerful synth/workstations available today.

I agree with the above post though, if you really want more power, save up a little more for the K2600. I have a K2500 and while Im extremely happy with it, Im still kicking myself in the ass for not waiting on more info for the K26.
