I just ordered the HR21-700 upgrade to replace an R-10 and H-20 receivers. DTv gave me an $100 rebate (thanks to the forum information I received) to use on the $200 HR21-700. There was a $19.95 handling charge and free installation was provided. I did have to make another 2 year commitment for the up-grade. My question is pretty simple, because I own the R-10 & H-20 is there any resale value for these units? If there is how much are they worth, I originally paid over $100 each for the units at Circuit City with the extended warranty program. Not very smart when I found out latter about the protection package DTv offered.
