Polariod DRA

I wanted to get a Panasonic DMR E85H but they don’t make them any more. One of the few with hard drive I could find is the Polariod DRA-01601A are they worth buying? For $100 you can’t go wrong unless it has lousy picture or something else wrong with them. Does anyone know if Panasonic plans to bring back a hard drive dvr any time soon.
