Since this is a vintage item, the cost is whatever the market will bear, wherever you're trying to sell it. I would suggest checking current prices on sites such as eBay, where one is currently being offered to sell at $200, while another is being offered for $90. The perceived value is what determines the selling price at this point, because the MSRP is long irrelevant by now, being that it's a discontinued item. If you need further help, I’m available over the phone at
