Bought D70s, D80 and D300 from Foto Forum in Phoenix. Never bought anything else from them though. (Why? Because they were the closest store to me with cameras in stock). Bought D200 from Mark Photo in Phoenix, along with some other (mostly lighting equipment). Happened to be in there trying to get broken D70s fixed, and bought D200 kit a couple of weeks before Hawaii trip. Would have bought a camera from Tempe Photo, except they are farther away - bought lots of other stuff from them (especially bags).
Much equipment bought from B&H, and had one return to them (defective lens) - great service based on my experience.
I've bought from local camera stores because a) all had the same MSRP price, and b) I was in a hurry and more willing to pay local sales taxes than wait a few days for cameras to ship from B&H or other locations. If one of the local shops would have offered a slightly lower than MSRP price, I'd have driven to them.
