Interesting...

I've used www.kitcomponents.com several times... always found what I needed, orders arrived correctly.  I guess your mileage may vary somewhat. The AeroCraft Parts (Lancair's answer to ACS) website is also active www.aerocraftparts.com, and although I confess that I haven't used it myself for ordering standard (non-kit-specific) components I suspect I will sometime in the near future.
