Thought I'd share:

A few weeks back I bought the Radio Shack DP-4073 piano for $299, which has been the rave on several keyboard forums. It's a 25lb hammer-action digital piano - I am using this as a MIDI controller to my Yamaha 9000 Pro (also using the PF and DX expansion cards). I took this a step further by modifying a QuikLok M-92 two-tier keyboard stand so the top keyboard sat closer to the bottom one. The result is a really nice dual-keyboard arranger rig with an 88-note hammer-action keyboard on bottom and an unweighted 76 note keyboard on top: the perfect combination for me, and they are custom-fit close together for ease of use. An added bonus is that the LittLites from the 9000 Pro also illuminate the piano. The entire ensemble looks, sounds and plays great.

Basically this cost me $300 for the piano and the time I put into cutting down the keyboard stand. It certainly got me a lot farther than wishing for Yamaha or anyone else to make a hammer-action 88-note arranger.
