the price is steep but not necessarily out of touch with the market. if i were you, i'd probably pick up the male since you already have a female pastel het clown to breed (at least eventually). the addition of the lesser probably wouldn't change your potential clutch odds all that much if you're primarily looking to produce super pastel clowns. plus you could definitely sell any het clowns next year with minimal drop in value, especially if they're pastels. also with the money saved you could buy a female lesser of breeding size and potentially kick-start the project if you really have your hopes set on a super pastel lesser clown.
either way, best of luck.
