First, on the reliability issue of Kurzweils - I've heard people I know tell me they had this or that problem with K's, but I've owned three different models and a module and never had the first problem even after extensive touring with them. Mine are rugged and still my top choice for a stage piano. I used to have dual keyboards with the 88-note Kurz's on bottom and a variety of keys on top. However I have taken it upon myself to reduce the amount of gear I carry so I mostly use just a Yamaha 9000 Pro on stage and have my Kurzweils in the studio. Now Kurzweil is coming out with the 61-note K-2661, and I'm thinking that might look good as a second keyboard over my 9000 Pro. Funny how these setups evolve.
