All Industrial Tool Supply http://allindustrial.com/
Good source of machinist tools and supplies. If you find something at their eBay site, but don't like the deal, call them on the phone and ask them for direct from them to you pricing on that part number, bypassing eBay. It works and is worth the effort.
I have had zero issues with these sellers. Everything has gone perfectly. With all sources, do your homework and find off site reviews (H-M!) of their products, and look around for the best pricing. There is definitely junk for sale at all of our sources, let the buyer beware!
