I have had a ReplayTV unit for about 6 months. I couldn't be happier with it. It is unclear whether my pre-production model has the same storage capacity as the production units, but it has really changed how I watch TV. I highly recommend it.

Video quality is better than anything I have seen from a VCR, and it is quite convenient.

I haven't read the review, but I would buy another one in a heart beat. (I would probably buy the middle model, for the increased storage space.)

BTW, the ReplayTV unit has firewire connections in back, which will come in amazingly handy in the future for Digital VCR's, etc...
