I'm now selling my second Tivo. I've updated the link below.
I have a TivoHD upgraded to 1TB (157 HD hours) for sale on ebay ending tomorrow (12/7/10 end date) at about noon EST. The link is: http://cgi.ebay.com/ws/eBayISAPI.dll...m=160521697766
I used a WD10EVCS (that an AV designed drive) for the upgrade and that drive has about 1.5 years of use on it. I can ship the original drive with the Tivo as well if you'd like. That drive has only about 1 week of use on it.
I also have the original box, manuals, and some cables.
Let me know if you have any questions.
