True, the cobolt steel bits are spendy when bought from a machine tool supplier, but TSC (yes, Tractor Supply) often have small sets, 1/16 up to 3/8, for $10. A nice full 1/16 to 1/2” x 64ths set in an indexed metal box from HF will set you back $40 to $60, but thats way less than machine tool supplier prices. The quality is probably not up to machine tool standards either, but they are really good by HF standards.

I just got a TSC trailer this last summer. Ditto on the Liscense bracket.
