The price = is better than any FPGA development/evaluation kit I've seen.and the PSoC D= esigner software is easy to start with. I'd be working on it now, but my wo= rkhorse computer is in storage awaiting my move. Huh, I never even thought of the PSoC. I did a project once with one about 8 years ago. A quick search even brings up an app note with a mixer project: http://www.cypress.com/?rID=3D2925 This might merit a bit more research...
