TiVo with rebate, now with 200% more hack

Tara points out that you can now get a $50 rebate on a Series2 TiVo. This is a pretty good deal, e.g. Amazon has ’em for $299 for the 80-hour unit (after rebate) or $199 for the 40-hour unit. Me, I’m waiting for the HDTiVo; in the meantime, I think I’m going to stuff another disk drive into mine to add some recording capacity. Interestingly, there are now 3 separate books on TiVo hacking: Krikorian’s TiVo Hacks (O’Reilly), von Hagen’s Hacking the TiVo (Premier Press; includes a bootable CD), and Keegan’s Hacking the TiVo (Wiley, not yet published).
The actual tools you need for the upgrade are freely available. In fact, I think I have a spare 40GB drive on the shelf over my head. Hmmm.
