leucistic leo, worth it?

[VI Reptiles]

Im just wondering what a good price for a leucistic leopard gecko is. I have been looking at one in a pet store and its $90.00 and its the coolest leopard gecko I have ever seen in person. Im hoping to buy it this week if anyone thinks I should go for it. Its not exactly the whitest I have ever seen (faded yellow). I was thinking of letting her mate with my male tang thats 50/50 patternless. I will get a pic up for my male A.S.A.P. Also, they have about 5 more leopard geckos which are a bit smaller and are 70.00 and im thinkin of buying them if they know the sexes.
