If you really want the gun and are considering buying it separately at an extortionate price, you should just go deluxe and then sell off the diorama base. Bases always sell and this is an especially versatile one.
Yeah this is definitely the best option cost-wise. You're going to have to hunt that gun and overpay for it. Resellers know it's an exclusive part so they'll obviously charge more for it. I bet it'll be at least $40, so might as well just grab the deluxe. The base will probably sell for $60.
