I'm pretty new to ball pythons, and while I'm tempted to say do what makes you happy... some of the other members have brought up very valid points.

One of the breeders I've been looking at charges $1250 for a pied male... whereas he charges $400 for an Enchi female, and I've been seeing Mojave females for $250-350.

If you really want to trade him, I'd try to find a comparable animal or a group of pythons that come close to what you can get for your male. I don't know if the site I'm looking at is over priced or average, but if it's average I'd want something neat like a bumble bee and an enchi in trade.
