I just got this http://www.thetoolwarehouse.net/shop/OTC-6612.html as I was looking around for a whole set of large sockets with no luck. Further I didn't know if there is enough clearance for a conventional round-shaped socket.

Free shipping is hard to beat, but you have to spend $100. That's getting hard because I have a lot of tools already and Harbor Freight is selling a lot of the "occasional use" stuff I am interested in.
