In my opinion, I would only shy away if they had more then one grade of "reconditioned."
In that case, I'd buy the upper grades.
For example, I bought a framing nailer from Reconditioned Sales, the official reconditioning source for Hitachi tools.
They offered two grades of tool, and because of the warrenty, I bought the lower grade.
Well, that tool had seen a great amount of use, and was a problem child to say the least.
They did replace the tool, and I upgraded to the better grade which has been a very serviceable tool and well worth the money.
I also recently bought a brad nailer from the same source, and this "reconditioned" tool shows little if any use.
Keep em coming!
