One of my two Tivo clients called today, 1 old Romio and 1 Bolt bit the dust. Client looked on Tivo website and all they have is the new Edge box. Any gotchas with the new box?

I'd love to put refurbs or new drives in but got burned on a refurbed unit from weakness with this client. Hours on the phone and multiple cable cards ended up sending the box back, couldn't get it to recognize the cable card.
