Sparkfun is a useful resource
Sparkfun has an interesting variety of products, and I enjoy "window shopping" on their site. Sometimes the price seems a little high, but then again there is often added value compared to "like" items available elsewhere. Sometimes I am willing to pay a little more for the added features. My principal complaint is that I paid what I think is a high shipping cost (and it was not premium shipping) and did not receive the items I ordered for 8 days. I order from other companies (not Amazon), pay less than half the shipping cost, and usually get my items in 3-4 days.
