I'm finally making the jump to Roamio, whoopie! I currently have a S3 HD XL in my living room and an S3 HD in the bedroom. I plan on moving the HD XL to the bedroom, using the Roamio in the living room where we do the most TV watching, and selling my S3 HD. My question is - where can I get the most for it? The good news is that I have a lifetime subscription attached to it, so I hope to get a decent amount for it. So far, I have only looked on the two places I'm most familiar with - eBay and Amazon. However, I'm seeing that an S3 HD with lifetime is fetching somewhere around $200-300, and this seems a little low to me for a unit with lifetime. Thanks in advance!
