Pastel het Axanthic value

I have someone I've sold to in the past asking me to trade his 09 Pastel het Axanthic male for a couple of my snakes. Frankly, I don't know the value of it and I don't want it to seem like either of us are getting ripped off.

Kingsnake has an 09 male for $450 plus ship

Not many for sale ATM

John has some on his website, http://jdconstriction.com/09Available.aspx

Most of them are sold so the prices are no longer listed. There's a female pastel het SK axanthic for $1000, she's 500 grams though.
