A NERD Pastel or Spider is no better than any others...just depends on what you like. I would worry less about the name of the breeder and focus on finding the snake that makes you go "Wow!"...then check out the breeder. If you don't think you'll run into problems buying from the big names, well...don't be so sure. There are tons of basement breeders producing some crazy cool and 100% healthy animals. And they're just as willing to stand behind their animals as the big names...and sometimes more...
If you find something you like, come here and let folks know...they'll give you the skinny on the breeder. Or you can check them out on the Board of Inquiry (BOI) at faunaclassifieds.com
And before you agree to buy anything, ask lots of questions...
