B&H and Adorama are increasingly my go-tos for anything with microchips. They've both branched out from photography to A/V gear to tech goods generally.
I run my list in the opposite order. Prices are generally just as good and I prefer to support those I trust first. Actually before I get to amazon I will search for small specialized vendors that might be more expensive but the staff actually knows something about their product, and so the web recommendations are good (they will of course recommend what they sell over an equally good brand they don't, but they are selling the good brands)
