I was just about to throw several HR10-250s in the trash that have been collecting dust for about 8 years, when for grins I thought I would see if anyone was paying anything for these on eBay. To my surprise 3 have already been sold this year for between $60 and $70. What can these units be used for now? They have an OTA tuner, but without a current DirecTV subscription you cannot get a guide or use them, can you? Am I missing something?
