Regarding the price, I agree 100%. The current retail price of the Mosaic is almost exactly the same as the Pronto. I'm sure you can set up the Mosaic quicker than the Pronto, but you will hit the limits of how much you can customize it just as quickly.

Regarding X10, people often ask will this or that remote handle X10, and the asnwer almost always is YES, as long as you have an IR to X10 converter box (IR543 or 4040).
