Hello All I need some advice. Here is My Current Setup: TiVo HD- lifetime Humax DRT800- lifetime Series 3- $6.95/ month grandfathered rate. I am looking to upgrade to the XL4 and doing away with the DRT800 Here are the option 1) Transfer the Series 3 $6.95 rate to a new XL4 (which will cost $350 for the box). They then told me I could get lifetime for the series 3 for 99 bucks. 2)XL4 plus lifetime for $699. Part of me want to go option number one since I will still keep the low monthly rate. It will take 4-5 years to make it worth buying lifetime. If I always have that monthly rate I figure if I want to upgrade to something else down the line, i'll be able to switch it to a new box, which you cannot do with lifetime. On the other hand, Who knows how long TiVo will honor the grandfathered rate? What do you guys think? Thanks in advance.
