That's J and R (very reputible outfit).
I assume this is a closeout price.
This is a good deal if you don't mind the previous generation box.
The DVDR80 has Free Guide+ Electronic EPG (forward around a week). In the US it only works for Over-The-Air and Cable (no Sat). Has and IR blaster and can control a cable box. Recorded events get the program title on the Disc Menu.
The DVDR80 can store 12 timer events.
The 80 cannot do a timer event on an ext input (for timed recording off an STB).
The Faroudja in the 80 could be a big deal if your using the progressive output (but many HDTVs do just as well or better with 480i and their own scalers).
Unlike the current models, the DVDR80 has no external venting fans (there's internal fan which apparently circulates hot air inside the box :a ). It runs kinda warm. I'd not place on top of a hot componet. I'd not place anything on top. No enclosed cabinets.
