Digi-Key, Inc.
They're the biggest, and maybe that inflates their ego a bit sometimes. While I've had good experiences with Digi-Key in the past, the most recent exchange left a bad taste in my mouth. I hung up during placing my order when, after questioning a 50% increase on the published price of some power supply capacitors, their clerk actually told me to "go somewhere else if I could find them any cheaper".
I did. I called Mouser (and saved a bundle, too).
... And the Ugly
Marshall Industries, Inc.
These are just about the most myopic, rudest, paper-pushing bunch of digidroids I have ever had the displeasure of doing business with. If it isn't bad enough that Atmel has given them direct access by placing them on their homepage as a preferred supplier, these teledrones go the extra mile to insure you'll get the least amount of benefit from your hard earned dollars. Minimum buys that escalate costs into the hundreds per order, scrimping on honoring sample requests, and just downright insulting email exchanges are, apparently, their preferred mode of doing business on the web. I can't, in any amount of clear conscience, recommend them to anyone needing parts, of any kind.
Marshall doesn't seem to think that placing this on my webpage is going to do them
any damage.
I invite you to join me in making www.marshall.com a world-wide cobweb.
