I have two complete 41 pcs sets of Snap-on tap and die sets; one metric, one standard. I found them at a house I helped clean out. Looked brand spanken new. I LOVE them, I now use them all the time to clean up threads and bolts. About $400 new. 
Oooh, good one! It's tough to beat a quality tap and die set, except when you buy a 40 piece set and find a very common metric tap isn't included in the set
