Too bad we don't have many pawn shops in the Mass! I don't think I have ever seen one. Buy a copy of the Want Advertiser or whatever that catch all magazine is, the one they sell everything from pet snakes to used tires in, there are some good deals on used tools in there. That is if you have the time to drive around and look at things.
All my work trucks have a Craftsman socket/wrench sets in them. As long as you keep water out of that plastic case they will last and make a great, reasonably priced tool set. If you see a tool guy running around (matco, snap-on truck, etc.) ask them for a catalog with SK sets in them. I have bought a few SK sets that are good as well and similarly priced to Craftsman. If you don't live near a Sears, but do live near the route of a tool guy, this may be worth thinking about as tools break and it nice to have them easily warrantied. I have a Sunex (Sunnex maybe?) combination wrench set in my jeep and think their quality is pretty poor, but they were very cheap.
