I'd hold off & invest in females instead. He's a nice looking animal but buy girls instead. A nice two-gene hatchling female or a few excellent quality single-gene girls. Otherwise you're forking over money up front, rack space & the cost to feed him for 2+ years before your girls are up to size. He's a nice example of those genes in combo but that isn't an extremely rare combination where you wouldn't be able to find another male in a few years if you elect to hold off. As far as the fader gene, I go back and forth on whether it's an actual gene or not. I know Outback Reptiles works with it quite a bit as do a few other breeders...juries still out on that one for me as to whether it's a stand-alone gene or like Satomi said, just extreme examples of line- or in-breeding to produce super-blushed out animals.
I just creeped your profile and you have the single normal female that would be of age (and size?) to breed to him if you decide to buy him. You could sell off those babies, keep back a few females and wait on your bumblebee to get up to size while pairing him to that normal female for the next year or two if you go that route. Just a thought; your money, after all, lol!
