If I was recording HDD I'd want at least a terrabyte hard drive.
We struggle big time with 160gb for standard def.
And if you record in standard def you might as well as pick up a stand alone unit for under $200.
You can also buy hard drives as stand alone units which will play divx, etc and if you connect it to your PC either wirelessly or ethernet you're having even more fun.
Personally I took the easy option and just brought a nice 22 inch screen for my PC. The missus gets the IQ and $200 PVR and I download stuff as I need it on my PC.
