Best price on grey import Nikon D7000

Hey, I'm looking to get some gear for macro photography. The products i'm looking at along with the cheapest price i can find are below.

1. Nikon D7000 body ($739 shipped from discount digital photographics) link
2. Tamron 90mm macro ($290 + $50 shipping from camera paradise) link
3. Sigma EM-140 ring flash ($398 shipped from discount digital photographics) link

Has any one else been able to find any better prices on these products? If not, are these sites reasonably easy to deal with?

Thanks
