Gene- Precise Bits has a good selection of tiny drills and endmills:http://www.precisebits.com/products/carbidebits/drills.asp?tsPT=wire. These guys sell resharpened bits at an attractive price: http://drillcity.stores.yahoo.net/index.html . Also, I recently found an assortment of 10 microdrills at Harbor Freight for <$5.
