B&H. Great prices and service. Went there dressed like a schlub and still the guy behind the counter treated me nicely, took his time with me as i was asking to see various Hassenblad and Rollei stuff plus the odd Leica trying to figure out what analog system i wanted to go with.
End result: Got the 503CW, larage flash and other Hass bits as a package deal from B&H. Sadly, sold it all 2 years later... good news is that i got MORE than i paid for it
Note To Self: NEVER AGAIN try huffing around a full Hass setup at audio shows. Awesome pics, but the sheer weight of it all....
Sadly, no really good camera stores near me and it is hard to beat B&H's selection and hands on try before you buy.
