I'm brand new to the arduino and I'm trying to build a water tank depth sensor. I started with the design in the Practical Arduino
book but decided to go with a design on the Freescale site.
I started to put together an order for the parts from digikey but discovered that for some parts they had a minimum order quantity of 2000.
I tried other sites (mouser, allelectronics) which seem more geared toward non-industrial supply but they didn't have what I needed. (0.2
mf ceramic capacitor, for example.)
Any suggestions on where to go for parts? (I'm in California.)
Have you tried surplus outlets for the parts?

I have shopped with all three and haven't had problems. Generally you should only shop the "big distributors" for parts if you are doing a large order, or need sourcing for parts for manufacturing (that is, where surplus won't do because the part might run out prematurely and not be available from another source). If all you're doing though is hobbyist stuff, go surplus first - then the big boys for anything else.
Oh - and ebay is another good source for certain parts drop-shipped from China - if you don't mind the wait.
