Has anyone read the contract in the $1.99 per month extended warranty? At their option; they can: 1. Pay you the depreciated market value of your 501, 508, or 721! 2. They can subsitute new equipment such as a 510 of a 508. Does this mean that they can give you a 510 as a replacement, and then charge you the new DVR fees? It just looks like you can't win, if they want to give you the shaft!
