Sure, supply and demand law will do its work but I doubt it will go down significantly. The cheapest way is to recast and paint it yourself or wait for recasts to show up on ebay.
Or part out and sell the rest of the figures without the bases and basically get the bases for free. Buttmunch seemed to have no problem getting people to bite on the bodies and hands for $130 or so. Sell the heads w/neck joints for $30-40 to go with Mark VI or BD Mark III, and you've about broken even right there. If you wait until these come out of stock, you could probably get even more.
One problem with re-casts is that they won't have the light-up feature.
Now buying recasts is acceptable in this forum???
