Ebay is a great resource for finding odd hard to find items. I've been using both ebay and paypal for many years and have had mostly good experiences with both. I have a few tidbits of wisdom to share with you from my experiences.

1. If you are buying, shy away from sellers who have a low number of transactions (less than 50) and also a rating of less than 98%

2. If you sell something on ebay and get paid via paypal- be careful because a buyer can get a chargeback order on the purchase transaction and get thier money back- even after you've sent them the item. So they get your item basically for free- so be careful with ratings and experience of buyers of your items as well.

Good luck!
