I did the same thing Daisycutter... needed parts and it was cheaper to buy a complete tank and have extra parts, or an extra tank when time/money allowed. Mine is in a rebuilding stage and awaiting Creeping Deaths new gun system. If you are into airsoft the new system reportedly will shoot 400fps! They are still selling their current Tiger turrets for $104 with free world wide shipping. I have one and love it! Laser machine gun to help you aim, recoiling airsoft barrel and a bad ***** tracer system for the glow in the dark Crosman BBs. It uses a small black light that charges the glow BBs and while I haven't checked the range with a tape meausre, I can shoot the house across the street from me!!

Well worth the money. I haven't heard what the new turrets are going to cost.
