Don't have any carpets but think they're stunning, I'm a boa girl myself.

I have seen Colombian normal babies for less than $100 though online: I'd check kingsnake and fauna classifieds. You could probably find a nice hypo for $100-$200 even too.

(BTW Colombian's arn't "true" redtails: "true" redtails are BCC's while Colombians, Hogs, CAs, and Nics are BCIs)
