You could also check out your local CTC store. I picked up a set of drill bits from 1/16 to 1/2 inch in 1/16ths, I beleive, as well as all the numbered and lettered bits in one case. I got it on special at 50 or 60 %off. I think I paid in the neighbourhood of $40-50. They are also titanium nitride coated. They may not last as long as a porfessional set, but for the hobby gunsmith, I think they should last a long time.
