Anyone have suggestions for a HTPC Remote (MythTV)?

I’d like to finally push my Myth box back and quit using a Keyboard to actually interface to it. Unfortunately there aren’t working drivers for the crappy IR remote that came with my cheapo TV card, so I’m looking at buying a PC-compatible remote.

What I’d really like is an RF capable remote that can be driven from a universal remote (eventually probably a Logitech Harmony 890). I have an RF Tuner for audio and since the audio is pumped from my Myth box to the tuner anyway, I’d hope to eventually flush everything into a single universal, and RF is a better choice than IR in case I ever want to put the Myth box outside of a line of sight location.
