"I know I'll be buying one of these. Giving how Casio prices their units I'm estimating the price to be between $450-$499 USD. The improved sounds (not that the 3500 sounds bad), more voices, styles, and that HUGE flash memory is enough for me to upgrade. I may have had to luquidate my synth monies due to medical reasons, but this Casio won't break my budget.

Dont know if you sold your drum machine...but the funds from that if you also sold your wk3500, would make getting the wk3700 not much a money issue at all. The medical stuff for more then money reasons.

Just hahah reflecting back on all the conflict you had picking a keyboard...looks like it turned out for the best. It could have sucked to spend lots of cash then just a month later have a new Casio tossed in your face.
