I'm looking to buy the Nikkor 70-200mm f/2.8G AF VR soon. I live in the UK and it costs ~£1100 (~$2200 USD), however I might be going to NYC for a few days in February and was wondering if I'd be able to pick the lens up over there. I've seen B&H recommended a lot on these forums and see they have a store in NY so am considering waiting and trying to pick up over there as I can save about £300. The only problem with doing this is whether I'd actually be able to get the lens. Are there many other reputable places I could visit should B&H not have any in stock? Any other options I'm not thinking of?
