/Edit: Retics that is.
Looking into getting one of these guys mid 2013. I know Bob Clark has a couple at the moment and that Prehistoric Pets have some morphs too but I haven't really seen many people who seem to be making the Super Dwarfs their main gig.
I've also seen a couple on Kingsnake and one on my local Craigslist but to be honest, I'm much less keen on buying one from someone who're more of a stranger in the business, I can't get landed with a snake that ends up exceeding 10 feet at the moment!
