I went into a local pawn shop today that carries a lot of misc. used tools, but the guy told me they were fresh out of used 1 3\16 deep wall 1\2 drive sockets but had new impact ones for $12. I think I'll wait on a used one and maybe a 30mm. I have a 30mm but it's a shorty and I can't tell if it would fit or not, so I'll wait untill one or both of them wander in to his store and pick them up for three or four bucks a piece. Hopefully I won't need to use them very often.
