Advertisements The title says it all. I actually picked one of these up for my HR20 but it will work fine on the TiVo series 3 also! $199.99 - 10% email coupon = $179.99 + tax. Just got one for local pickup. I have had one of these drives on my PC for about 4 months and love it! Coupon was in last nights circuit city email. Enjoy!
