>>5959651Should be SP3rd. He should be within the 3k range from my last searches and also the easiest to obtain. Most expensive would be SPIV but since I ever rarely see SP1st I'm not too sure. I do know SP2nd is the priciest one out of them if you want blue and the ORAORAORA soundplate.
>>5959664I've speculated this pretty often way back when for Tusk since Tusk Act IV is big and bulky enough to justify a stand alone release with Tusk Act 3 being packaged also. Act 1 can easily fit as a sort of floating figure above Johnny's shooting hand and the Act 2 being packed into its own bag behind the plastic tray or packed on the bottom row if they want to retain the standard box size.
