CO Alarm

Since I am new to this where do you guys prefer to order your parts? I'd like somewhere in the U.S.A. that is priced reasonably with fast shipping and good customer service. Of course I'd pay slightly more providing the last two criteria were exceptional.

I buy most small parts from digikey.com, mouser.com, and jameco.com. All three have inexpensive Priority Mail
shipping that typically takes only 2 days. They also all carry a lot of Arduino stuff nowadays, especially jameco.
