There's two big advantages to buying off ebay. For one you have buyers protection in case the item isn't as described. So if issues were hidden, if there was foul play like being sold a stolen item, etc, then you have some financial protection from paypal. The second advantage is that off ebay it will typically be a retailer which means you get an invoice, they declare the profit from the sale and hence you can tax deduct it if that's applicable to you. So while it can seem confusing to some why anyone would spend more to buy tables from ebay, at the end of the day a $9000 ebay pinball machine is actually somewhat cheaper than a $7000 cash purchased machine, and you have some financial protection as well.
