Generally with the 3 car limit - it sells for close to $300 new. Worth about $200 if it has 2 cars remaining. Worth about $100 if there is one car remaining.

So if the unit you are considering has 2 cars left, and you can get it for $150, that's a good deal. Mine didn't come with a plastic case. The software is downloadable. So the only real important part of the whole thing is the cable.
