>>if you go to a reptile show you can get one right then and there. i don't like the idea of getting one shipped in the mail. who knows if it will arrive alive. plus at a show you can look and all kinds and pick one you really like.
>>i recently bought a baby motley butter corn. it was one of the prettiest ones i saw. there were 2 motley butters but the one i bought was more prettier and more active. plus shows are a blast!!
Now is pretty much the tail end of the selling season. Breeders still frequently have a lot left, but the best ones are usually long gone by now. Whileon that topic, I also like picking out my own at a show, but as a breeder AND buyer, I usually buy the snakes LONG before a show. My BEST 25% or more were ALWAYS pre-sold before show season (and even hatching season) even started! Want the best? Put a deposit with someone with great breeders NOW for 2006 babies. I just did. 
In other words, maybe you can pick out the best at the show that you like the most, but only the breeder(s) can pick out the BEST that don't even MAKE it to the show for you.
Not to be nit picky, but it is illegal to ship/receive snakes in the mail. You must use a common carrier (like Fedex) or airlines (like Delta).
