Ouch... Yeah, that's more for a quick sale and even then, for $500, it better be a proven breeder with either trans or hypo showing. Without knowing what he carries, that would only create hets for sure and if you were lucky, you could get trans or hypo babies. If you get serious about breeding him though, I'd recommend finding a good dragon breeder in your area, talk to them, get to know them, and pick their brain about it BEFORE getting any girl. That way you have a support system and some honest feedback on where to go with breeding instead of someone seeing a sale.
