Charley, The PSR 2100 offered a lot in features for the money,,it had some downfalls for my needs, poor keyboard feel..lack of a good 16 track sequencer, and poor sequence playback[partically drums]..there were some nice sounds, but overall I prefer Roland GS sound engines..I was not impressed with the construction quality...the arranger section, pads, vocalizer, are very good...basically Yamaha tried to include the goodies, but at the cost of quality...I shipped my PSR to it's new owner this afternoon..and happily going to check out Roland EXR 5 for imediate needs[a keyboard that I can leave on the job], untill Roland releases it's new flagship arranger...When I really need to be happy playing, I still use my G1000..I wish the best to Jose[the new PSR2100 owner]......what a relief...No more Yamaha....BTW ..Casio 3500 may work for me in a band situation,,I mean..who would steal it?
