I think you just need to look around for a sexy yellow belly. I was very picky about mine and I finally found this gal this year and I was blown away.
I don't know what line she is but I think she is awesome. SnakesRkewl has his own line and IMHO are much nicer than the bling yellowbellies.
NERD is like other big brand name company's in my opinion. You pay a lot more for the name. Are his yellow bellys different than the next guys? I really don't know but you can find nice ones anywhere. You just gotta kick some tires first. Good luck!
