One great thing about Digikey is that you can order in the late evening (if on the East coast, evening on the West coast), know that the product is in stock in the quantity you want, and get it by 8:30 or 10:30 the next morning. That's like 14 hours. Pretty damn amazing, though the FedEx/UPS early AM shipping is $$$.
Digikey has stock qty info on their web page.
For stuff not in stock, they give you (IME accurate) lead times based on your requested quantity.
