Proving him out would be a really good financial investment. Female albinos seem to be going for $500-$700, pairs of hets for $225-300. If you decide to go with a het female, go for a pair of het albinos. It seems like there are a few breeders that will sell a female for around $200 and then throw in a male for an extra $25-50. Not a terrible ideal, just in case your spider proves not to be a het.
However, odds of proving him out are better with an albino (50%). Odds of proving him out with a het female are about 25%.
