Thanks all! I am thinking McMaster may be the best bet. I want to check with a couple of local suppliers on Monday first. It is a zona set that I got from the R/C dealer. Under a microscope anything smaller than #70 is not sharpened with a tapered point. Very poor quality in my mind. It is doubtful that I will ever need the smaller sizes, but if I am paying $25 bucks for a set, I think they all should be useable!
