A bit late - sorry. jon, the MX-700 is an absolute gotta have. Can't overstate that. I had the Sony RM 3000 and it pales in comparison. The powerful and flexible attributes of the MX-700 are unbelievable. Also, you can downlaod the MX-Editor software and programming manual from Rempote Central (MX-700 files section). The real beauty is that you can icopy/paste Pronto/Pronto Pro .ccf files into the thing. Remote Central has almost 7000 different component files in the Pronto section and another large group in the MX-700 files section. Most of the input to here on this thread talks to the satisfaction of the 700. You'll wonder how you lived without it.

Good luck with whatever you choose.
