Modified Slime Blower Prop

Can anybody tell me where I can find a Super Soaker CPS-3200?? I looked on eBay & there was only 1 for sale at $375. I know its a rare item, but I’ll go as high as $150 & it doesnt have to actually work I just need the whole toy intact. I’m going to repaint it & add lights/extra materials to make it a modified Slime Blower. Hopefully i can have one before the NY Comic Con in October. Please help…

All i have is the 1500.
