You could dive into the world of URC Complete Control (CCP). You can find the MX890 or MX990 for sale at good prices (avoid the MX780). You just need to make sure the person you buy it from, supplies you with the programming software.
I'm gonna guess the programming software runs on MS-Windows? And
perhaps Mac OS X? That'd be a non-starter, as we currently have neither. (Though there may be some Macs in our future.)
