I've used sparkfun only and the reason I like them best is for the support, the easily navigatable website, great user and customer support, and the wide variety of products they sell. And I've had email conversations with many people at SparkFun, why didn't you think they did that? Their prices may be a bit high for individual parts, but that's what we have digikey and mouser for. they even recommend buying from other places if you order small pieces like that in bulk. Also, if you complain about the price being so high for whatever product and show them an example of the same product somewhere else for less, they'll either tell you why their part is more expensive, or they'll lower the price. Sparkfun isn't just an electronics website--Their a family!! Plus, where else do you find so many great tutorial, daily videos/posts, and awesome people like that?
