I expect the Star Destroyer (if it ever makes it to market) will be sold in numbers less than 250, maybe even less than 100. They'll definitely sell out fast and skyrocket in value. I imagine a lot of sacrifices will have to be made for production. There's so many undercuts and details on the original filming miniature that would need to be filled in for the EFX bird to withstand injection molding or casting.
I think a collector wanting an unlicensed one-off build would pay $20-25K for one, easily. So the price tag is not bad imo. The big question is if people want to indirectly support as shady a character as Steve Neicen (heard so many horror stories over the years). Some people are saying he's built his entire enterprise on float funding, taking payment for kits he very rarely ever ships unless you happen to be one of his friends or partners. Makes you wait until Paypal buyer protection expires, then ignores you until you publicly shame him. Like this poor fella on the Replica Prop Forum:
After the debacle with the scout helmet, good luck anticipating folks are going to feel trusting enough to put down a fat wad of cash for the preorder.
