Just my two cents . . .  
 
I would think that something like that could be set up with amazingly tight disclaimers so any potential liability would be extremely slight/negligible, if it existed at all.  
 
Let's face it, this stuff is really hard to find on eBay, and e-MusementParkStore has almost nothing in stock. 
 
Pleeeeze, Mr. Jeffy, sir, think about it some more?
