I would not under any circumstances pay extra for a het pied normal unless I was going to breed it in the future. If you want a normal, there are many a breeder that all but gives them away, so paying $200(just a number) for a het pied for a pet will net you absolutely nothing. The other three are all visual morphs, so they are worth more to you even as a pet than a normal, so they all make sense. If it's a pet, pick the one you like the look of best, and if possible, in the case of a pet, handle before purchasing so you can get to know it a bit, see it's temperament, etc. No point in getting a pet BP if it's going to snap and hiss as you every time you want to hold it.
