I have had a Key61 for about 10 months. It feels great to me. You get enough resistive bounce to play as fast as you'd like, but not at all springy like a cheap keyboard. Comparing it with my Yamaha SX900, the Key61 is a little bit noisier, slight clunk when you play any key, audible when switched off, but this can't be heard when playing, so absolutely not a problem. The SX900 is silent but could be described as slightly spongier. Great advice to try it in the shop of course, but for me the Key61 keybed has never made me anything but happy. I'm sure you will adapt to it far more easily than a fully weighted keybed.
