I'd say a good price to pay is what I paid... but steals like that don't come around often! $250 for hatchling male and a free het female to go with it. If I didn't have that opportunity, then $350 for a male is the most I'd probably part with for one, but they can be pricey. If you like him, offer or pay the most you are comfortable with, but no more than $450 IMO.
