If they can sell elite ponytail hair for $29.99 at some stores (which btw is on fastgrab, and can be reduced with a sharecg coupon to $3.99....teehee!), then you can sell this ship for $24.99!  The thing you need to consider is that "I believe" only 1/4 of customers will probably buy it at actual cost, and most will wait for a sale.  (I typically always wait for a sale)  This is how this market works.  So knowing that....your price in a 30% off sale would hit $17.49 or so.  You need to decide if that is OK with you.

I would also highly recommend getting some GOOD promo renders!  Maybe offer it to a couple of skilled artists free for good render promos?

BTW, does it have anything on the bottom where a smaller ship or land-craft can board? (like a sloping down platform/hatch?)  Any landing gear?
