Billed as "silicon valley's electronic marketplace". They have a good selection of parts, and I am told their retail store is a must visit for makers in CA.

Yet another surplus place.
Wide range of parts and "stuff".

One of the best and oldest surplus places around. And the are in Moorestown, NJ (buy local).

Yet another surplus place. Seem to have low prices, nice hardware selection, lots of relays and potentiometers.

Good test equipment site. Educational kits and the normal component selection.

"$20 minimum for merchandise, shipping extra. For orders less than $20, an additional handling fee may be charged."

They have been in the surplus biz for 50 years, and it looks like they still have some of their original stock for sale!

The web site looks decidedly low tech, but they have some amazing stuff.

This is the sort of place to look at when you really don't know what you are looking for!
