I agree, stay away. 99.5% feedback is not that great. Looks like they may be doing some shady business judging from the negatives they have received. I am partial to B&H so I would point you to them. They are rock solid and I have done business with them with no issues.
Just to pile on with one more opinion, I agree that saving $100 and forfeiting the USA warranty isn't an option I'd remotely consider on something as complex as a D7000. You'd also be buying from an unknown entity rather than dealing with a rock solid company like B&H, Adorama, or Amazon. The add-on warranty those guys are selling along with the ebay auction would make the cost more expensive than getting the camera and lens with the USA warranty from one of the reputable dealers.
Since you're in the US, I'd go for the Nikon warranty. Even here in Oz I went for a non-grey market D7k for the body warranty. Bought other accessories from HK as they have 1-yr Nikon international warranty on accessories.
Having said that, I wonder what the turnaround might be to have body repairs done through HK. Like my body has been back to Nikon in Oz twice. First time was an issue with non-G lenses. That took 6 weeks to get a PCB in from Japan. Second time was the dreaded oil splatter. Still took a few weeks to replace the mirror drive motor. Some of the HK sellers give warranty that includes 2-way express freight to HK and I suspect may achieve faster turnaround than Nikon Australia!
You do your research, make your choices and roll with the blows...
