Need help choosing a breeder...

I am going to be attending the Mid-Atlantic Reptile Show quite soon- about three weeks from now. I was thinking of picking up a Leopard Gecko, but now that I've had some time to get used to my Corn, I am considering another snake. I think I want something a little different than a Corn, but still a good pet, so I am thinking either a Ball Python or a Mexican Black Kingsnake. I've also had good experiences with a California Kingsnake, so I wouldn't be averse to one of those either.

The only thing that worries me is that I sort of accidentally stumbled upon a great Corn Snake breeder (she answered a message I posted on this site back in May!) without really knowing what to look for in a good breeder.

I was a participant in a chat at CornSnakes.com a few weeks ago in which some more experienced members detailed the ins and outs of Crypt, and it freaked me out a lot. I can and will quarantine the new snake, but you really cannot quarantine for Crypt (from what I have read) so choosing a good breeder is essential.

So what do I look for in breeders at these reptile shows? Here are the breeders that will be there:

LLL Reptiles- have heard bad things about these guys from Bearded Dragon people
Maryland Reptile Farm- MD [pretty much anything]
Prairieland Herpetoculture- IL [BP, colubrids- maybe Kings?]
Regal Reptiles- RI [anything & everything]
Reptile Kingdom, Allen Booth- NJ [KS/MS/BP]
John Skipper Reptiles- MD [BP/KS?/MS?]

Some unknowns (no specialty listed- could be selling anything!)
Rick Krumrine- ? [?]
Ted Lascola- WV [?]
Robert McIvor- MD [?]
Randy Wright- ? [?]

Again I appreciate any and all responses. If there's something you'd like to say about a breeder, but don't want to air in public, feel free to PM me. Thanks very much!

Have you had any luck with any recommendations or input not shown here?

lol Nope. I ended up getting a new Corn hatchling, though I am still wanting a Mexican Black King really, really bad.
