John--
I often deal with
Wesco when I need stuff at work, and they're always nice people to deal with and have a LOT of stuff in stock.
M&M Aerospace is another good outfit to deal with.
Prepare yourself though, I know at work, even though we place hundreds of orders with these and other outfits a year, every place we deal with DOES NOT hesitate to say "bend over" when we order smaller quantities. I've seen things marked up almost 20X from a small quantity order (say 10 pieces) to a larger order (say 1000 pieces).
If you want, I can look up the part number in our system at work to see if/when we have ordered them and the prices we paid.
