I would also look into a female het pied. You could get a pastel het pied, or a ghost het pied-that will be really pricey though. Recessives take a lot longer to work with, so IMO there's no sense in getting a bunch of recessives if they don't have mates.

I can't say for sure how much she would be, ghosts have really dropped in price, I know I was seeing males in the $200 range, so $300-$350 for a female is probably close, I can't remember for sure.
