Are there any dom or co-dom moprhs for sand boas?

I have always been attracted to these stumpy little guys and gals. Is there any good sites on descriptions of morphs. I really want one of these guys but ill wait till my red tails and balls start breeding before i jump into another moprh. It never hurts to do a lot of research though!

Here's some good info from vpi's website.
