Do yourself a favor greyleopard66. Buy a used Pronto Professional TSU9x00 remote and RFX9x00 extender off EBay and call it a day. (I use TSU9600's in conjunction with several RFX9600's and one RFX9400) The editor software, ProntoEdit Professional (I recommend PEP v1.1.20) is free to download here at the site and the Pronto Professional forum and files section will be a valuable resource for you. Going the Harmony route will be a step down compared to the URC remotes that you have owned and the Pronto will be a significant step up over anything you've used before in my opinion, including many of the current offerings which are comparable offered by other manufacturers at 2-3 times the price even on the used market, not to mention those other products are dealer protected like certain URC lines unlike the Pronto Professional line. Just my two cents in the event you are looking for alternatives to URC.
