For anybody who may of been looking for these, I manage to find a guy who currently has some, both the Rufous Beaked Snakes & Red Spotted Beaked Snakes. Nick @ FirstChoiceReptiles has like 7 rufous, and i'm not sure how many red spotted, his prices are very very good though, only thing I don't understand that on kingsnake he lists them for $100 a piece and on his site he lists them for $80 a piece, so if you purchase them say you seen them on his site.

Rufous beaked snakes(rhamphiophis rostratus): males $80ea pairs $150

Red spot beaked snakes(r.robopunctatus) $250/pair
