where do you guys prefer to order your parts?
As you mentioned you don't get good, fast and cheap at once...
Paying for DHL/FEDEX (about $17 for a physically small order) will get you fast (2 to 5 days) from China. Some Ebay sellers will do it.
DISCLAIMER: Mentioning stuff from my own shop...!! Leave now if you want 
I am trying to provide Good, Cheap (on-the-Shenzhen-Street prices) and Fast-If-You-Want with http://YourDuino.com PLUS lots of How-To on the http://ArduinoInfo.Info WIKI. Plus a live (if aged) Engineer who answers Customers's questions. I'm having fun, being very busy, and making a little money added to Social Security so I can buy my wife an Iphone for Christmas. Don't tell her!
Seriously, please critique the WIKI, suggest new topics, and pass the link along. It's at about 2000 hits a day, which motivates me to keep on adding to it.
