Phew, thanks JuniorJam. I just squeaked in on the deal at the Washington service center and nabbed what the CSR (Elizabeth, very nice) said was their last one for now, a PVHS2000 refurb unit for $279 + tax and shipping. I would have preferred the 1000 for $229 since I'm going to upgrade the hard disk anyway, but they didn't have any of those left.
My 20-hour ReplayTV from buy.com just arrived yesterday and it impressed me so much that I had to have another one. My only nagging fear is that the service will somehow change in the near future. I base that on the fact that since upgrading the software last night to Rev. 3.0, there's this nag screen that keeps popping up telling me I need to register my unit.
