I was getting a little nervous with the age of my 665, and it would restart just about every time it accidentally knocked to the floor. Decided to look on Amazon to see what was available. Everything was refurbs as far as I can tell, but one seller was selling a refurb for $104, which seemed to be the cheapest out there. Had some free bucks from my credit card that could be applied, so I ended up buying the refurb unit for around $65 out of pocket.
Got it yesterday, and looks brand new. Pretty easy just hooking up and cloning my other one, so that was pretty painless. I'll pull the batteries out and store it someplace safe until I have to have it. Got a son that is fascinated with remotes, and fear it will come up missing if I don't.
