I like possible het females, at least from a buyer's perspective. This year I've started amassing a small army of morph poss het recessives. (They were originally going to be ALL females, but I did wind up with one male that I just couldn't pass up ...) They are WAY cheaper than buying guaranteed het animals -- the majority of them cost me little more than a stellar example of that morph would have anyway, and they're all really nice looking animals -- and I figure that if even a couple of them prove out, I'll have come out way ahead.
I agree with Rat160's sentiment that I really wouldn't want to do any breedings that could produce possible hets if I can at all avoid it -- I'd want to know for sure what I was offering for sale, plus of course greatly increase my chances of hitting on visual recessives. As a buyer, though, I've become a big fan of possible hets as a fun way to build up my recessive projects inexpensively. (... We'll see whether or not this is really such a great plan in about a year or so ..!)
So I guess maybe if you try to market them from that perspective (cheap way to build up your lavender projects!), plus maybe some enticing group shots with your visual animal, that might help move them out ..?
