Theres some guy trying to sell me the exact carpet python (looks wise) its a male and I think he told me 3 or 4 years old. However $325 seems a little extravagant for him though it does include a tank. If your in the florida region you could probably pick him up. Though its not going to be a 7-10 footer it being a male and all. I've tried looking at albino boas and found them all pretty expensive so if you find a good deal I'd go for it. I have a boa about to hit 7 foot and they're great snakes. Most docile thing I've ever seen. If your in the Python department though Macklots have always been one of my favorites and they all seem to have a great feeding response as well as looks.

good luck
