I  love my TiVo Series 3.  It has a great Spousal Acceptance Factor (SAF) and though the price was crazy high, it has run flawlessly in our family room for months on end and I can't seem to fill it up with content.  

If you're interested in a Series 3, TiVo has a great deal at $499.99 + free TiVo Wireless adapter here.

Now if they can just get that whole TiVo to TiVo sharing feature running again...
