I suppose the thing is that I want to get a fair price for the current market; I don't want to take anyone to the cleaners, nor do I want to be taken, if that makes sense. The prices I see on eBay are so all over the place I'm having a heck of a time even nailing down a range. Sold prices looked in the $500 range, but for-sale prices were just crazy, hence asking here.
Also, I didn't find anything for Mario Brothers or for Sorcerer's Apprentice at all, so I don't know how the title will affect the price.
Anyway, thank you for your feedback, high voltage.
