ReplayTV.com has Refurb Replay TV units with a lifetime subscription for pretty cheep. Toss in coupon code RTVD10 for an additional 10% off.

After borrowing one from a friend, I have now ordered one of my own. As far as I am concerned, there are tapeless VCR devices, then there are true DVR/PVRs like the Replay. I've set mine up to record several of the ReplayZones so that I have miscalenous content any time to watch, either via my TV, or at my computer. All with no hacks to the unit.
