My friend just replaced the harddrive on his pvr a few months back. Mem express had the exact same harddrive back then. I think the motorola pvrs are limited to a max 160 gig harddrive.
Looks like they are $60 and $65 still.
I can't believe the harddrive isn't crapping out faster on the pvrs. It runs sooooooo hot. i should really buy a harddrive now in case they stop carrying the 160gig ide hd.
