tap and die set?

Thanks everyone for all the great advice and links to products. I did plan on spending what is needed to get good quality taps and Bohica2xo is correct that I really only need a few of the good ones. My old tap set (30 year old Hansen set) is still in good shape except for 2 taps and 1 die I have worn out using them on stainless so I think I'll just replace those pieces and keep them for the average stuff I do and look for a set, or just the few I need that'll take care of tapping the stainless I do, which btw is generally 304. Bohica2xo that's very interesting about possibly using the wrong cutting oil. I just assumed all was needed was a lubricant and have always used the cutting oil that my local NAPA sells. I'll read up more on that subject and make sure to use the right stuff from now on.

Thanks again for all the input.
