Here's a 2003 D110 that some one is selling on eBay. Looks like the guy/gal is going through the effort of making everything US compliant, so it's a mater of swallowing the price tag.
There is some question about warranty.
I tend to like the D90, but with a family, the 110 starts to make more practical sense.
