I know it's not a "brand", but I figured it's cheap enough for a 1TB to be worth posting. I saw them instore as well, and they did in fact have a $299 price badge in the shelve (the "pile" had the reduced price of $145). I am not sure how good it is, because it's not very googleable (probably a rebadged version of something else), so can't be too sure of the specs. It does have USB inputs: 1 for input, one for allowing a pc to access and copy recorded files.
Model is "PVRHD1TB" (yeah, not very imaginative)
Its always the software that lets these cheaper PVRs down…. and yet I have an old topfield 7100HD that is still fantastic.
