Tivo has cut down the price of its lowest recorders to just $50. This is after rebate. You have to shell out $200 first and you’ll get $150 rebate check several weeks later. You’ll get at least 40 hour recording time on the Tivo unit. See article here and you’ll find the rebate here. I’ll say buy the cheapest unit and slap a bigger hard drive on it, although this requires a bit of knowledge of Linux.
