Again as others have said, very hit and miss. I bought a chainsaw chain sharpener, plastic but used it for two years, at $6.00 a sharpening per chain, it more than paid for itself. Dad bought a couple of hammerdrills for some cement work, the first one did the 3/4 of the job while the contractors went through two DeWalts getting his 1/4 completed. Dad gave me the second one (wanted the "good" one!) as the other new one will most likely be like Stu's. Have bought tools for the tractors (no problem if lost in the field) and for the girl's first tool boxes. They have their place but wouldn't plan on them for earning a living from.
God and family, the rest is icing on the cake.
I'm so far behind, I think I'm in first place.
