It could be a lot worse. I ended up taking a four foot four year old female boa that had been stuck in a 20-gallon all her life and fed minimally "so she wouldn't outgrow it".And no I didn't pay a dime for her.
While that male needs an upgrade, at least he does have enough room to stretch out and his body condition is decent.
IMO as a common male he's overpriced, unless the tank holds water and can be flipped to someone who wants to use it for fish.
