I used to use Partminer and thought it was awesome, but I stopped using it for some reason... Maybe it turned into a pay service, I don't remember why.

This site has saved my butt. It found a critical component used in my kits when all the others (Mouser, Digikey, etc.) report Out of Stock and 4-6 weeks lead time.

This is an early startup and the people running it are cool.
