baby albinos go for around $250 for the regular albino like the one shown in my pics. Adults can go for alot more (400+ I've seen), and even more so if they are female. There are also different pattern variations which 'cause the price to go up even more. Then the regulars are available for anywhere between 100-200 for the babies.
Of course, if you keep your eye out, you'll find one in the paper going for really cheap or free because alot of people don't realise how big they get before buying one, then they just want it off thier hands. (That's how I ended up with my guy.) We built a 6'long by 2.5'deep, by 4' high cage with multiple levels, variation in temperature zones, and large branches for him to climb on.
