" it would appear the item might be to good to be true"
If you think like that, why did you buy it?
If you do not pay the seller, he will most likely file against you in order to recover the fees eBay has already charged him for the transaction (eBay charges sellers a heavy fee the minute an item is sold, regardless if paid or not).
Eventually, by not paying you earn a "strike" on your record.
A few strikes and you may lose your privilege to transact on eBay.
In fairness to all sellers, next time you see something "too good to be true" hit the "back button" instead of the "buy-it-Now" button to regret or question your decision the next day.
