We bought our Champagne from them in late 08 and we can say when spending that kind of money we wanted quality and we got it! He came healthy the only bad thing was he didnt breed the first year. Picky little dude!
NERD does have some gorgeous champagnes I'm jealous you got one.
I can assure you that NERD's animals are nothing short of perfect. My collection/projects consist mostly of their animals, and they have never given me any problems. I know many people that also own thier animals, and they have not mentioned anything negative either.
