Why not purchase a used Pronto Professional TSU9x00 remote and extender off EBay and call it a day? You couldn't pay me to use any of the alternatives out there at present as far as conventional remote control solutions go and any of those solutions that do offer a similar level of customization and flexibility will be protected lines where the software isn't freely available to download. No thank you. The fact that the Pronto line of remotes has been discontinued is irrelevant as far as I'm concerned. So long as there is used inventory out there the choice should be clear. At least it is for me.
