Try the link now. I have no idea why the original link was bad.
I bought the JNC660 for my RL. It's now $100 with Prime shipping. I put a $70 one from Costco in my wife's Pilot. Either seems adequate, but I think the Clore unit is a better unit, perhaps overkill.
I also got the Solar ESA30 (12v to OBD2) adapter for the keep alive function offered by the JNC660.
