Again, I believe the color determines if it's a thin ring 3700 or thick ring 3800. I always forget which color denotes which, but I did have a red craftsman with the power sharp addition that was a thick ringed 3800.I would have to say 3700 is harder to find, than a 4000. Unless you want to go with the Craftsman 3.7. Those seem to be out there in good numbers. I guess that is a result of being sold at Sears, where the 3700 Poulan was sold through dealers.
