What was the buy it now price?
The PayPal buyer's protection has never left me holding the bag on an eBay purchase (not the case buying off eBay and paying with PayPal). How long can you be out that much money? I just had to get a refund on an international order that was never received, it took about 6 weeks from the time I paid until I got the refund. If you have the money laying around it's probably worth it to try to save $1500-$2000.
