WeaKnees upgrades and CableCARD info

Weaknees has launched upgrade kits for the new Series 3 TiVo. Since the box is single drive only and no external (though someone did hack their way into adding external storage but I wouldn't recommend such drastic measures), these kits range from 500 to 750Gb drives that offer up to 60 and 100 hours of HD recording.

They also have a handy table of CableCARD  pricing that summarizes a lot of blog and forum posts.  I should note that while Comcast told me my two CableCARDs would be free, my first post-TiVo monthly bill says they are charging me $1.50 per card, which isn't enough to complain about but still kind of weird since they said it was free from the start.
