Looking for auger bits for a stanley hand brace, and new ones are expensive ($10-20 a bit and up). I see some used/vintage on ebay and wondered about the quality of different brands, what to look for in terms of usable bits, etc. Many come in a 3-level boxed set, some look pretty rusty.

Saw a set of "Jennings pattern bits made by Swan"... anybody know those?

Or a more reasonably priced source for new? I'm not anxious to develop my skills as a drill bit refurbisher...

Thanks-
