If it's not there, then you're buying gray market. No difference than buying it from a random ebay seller as "new." Plus, typing Sunset Electronics, either alone or with any other search terms, into google brings up enough horror stories that I'd buy used from Craigslist before dealing with an outfit like that. Missing parts, bait and switch, etc. NO thanks!
When you're sending $900 sight unseen to a merchant you've never dealt with before, you'll want to be sure that they have a pristine reputation. There are way too many dodgy electronics stores, particularly in the NYC area. I used to walk by them every day on my way to work, and could tell they dealt in gray market goods. B&H or Adorama was always more expensive, but it was worth the peace of mind to shop there.
