Great catch... The $9.95 service is the real steal in the deal, though I thought accounts were grandfathered into the service pricing, not individual units. (I've never paid monthly though, always bought lifetime)
You still might consider upgrading to lifetime on the box. Even at the great $9.95 price, you could pay off the lifetime in less than 3 1/2 years.I just called TiVo to transfer a used Premiere TiVo box to my account. The box is a recent replacement under warranty by the eBay seller. Mfg date code is 18-OCT-11. Box in great shape. Paid a little less than $60 delivered to me.
It is grandfathered at the $12.95 price, and with my MSD it goes to $9.95. I bid on several boxes, but the all were bidding up to over $60. I wasn't even aware of the grandfathered service pricing when I bought it.
As my wife says, I fell off the turnip truck at the right time. This box had just had a buy it now price added to the auction when I did my last search for the night. I jumped right on it.
