I can't decide between a Plus and a basic. I really wish we knew if these could be upgraded ourselves. If they can I'll probably pick up a basic from TiVo, with free Stream, and a 2TB drive from Amazon. I should be able to sell the Stream to offset the cost of the drive and get a 2TB upgrade for free. However if Weaknees has some secret sauce that makes it so only they can upgrade then I'll probably just buy one from them.
