If you log into your account at tivo.com, the pricing will be displayed for you. nirisahn, I would guess $299. One thing we noticed on the site is that the 'popup' that appears when you get the plan details is showing the older promotion information on one of our computers, and the newer info on a different one. MickeS, your next TiVo purchase would cost $299 for the lifetime service. I don't think you can do any transferring, but you should also be able to (and should have always been able to) purchase a lifetime on the 2nd unit you have, but that is something I'd check with TiVo on. A new Series3 and a new TiVo HD should last about the same length of time, the most common failure point in either unit is a hard drive, and that is easily replaced. Beyond that, its essentially a crap shoot. But, the Series3 will disappear from the market sooner, rather than later (unless something changes) so if you value those extra features, you may not want to wait too much longer. But all in all, these units are pretty much the same.
