This is a LIFETIME Series 3 (TCD652160) with a just upgraded (April 2, 2013) 2 TB drive. It allows for 318 HD hours! It also looks like the day we bought it from TIVO. Perfect condition, with the Box and all original books and accessories! I even tested and verified that the Power Supply output and Caps were perfect before installing the 2TB drive. I do not see how you can find a cleaner Unit anywhere! Reason for selling after just doing the upgrade, is that TIVO made me an offer on a Premiere that we could not resist! Notice that the TIVO is powered on (see light in picture) and connected, but the cable card is now in the Premiere. Price is $350 plus actual shipping , and I use PayPal.
