I've got the Directivo (Direct TV/Tivo combo unit). I've added an additional 120gig hard drive for a total record time of approx. 149 hrs. I'm waiting for that CacheCard (http://9thtee.com/tivocachecard.htm) to come out cause it does take a few seconds to change between menus, but I love mine. I bought it a few years ago when the cable company tried to jack me for their internet access I never had (HELLO......ADSL installer for Bellsouth - 40% discount for employees, why would I have their crap?!?!?!?) Anywhoo, I love my unit.
