Despite all the douchebaggery of Ebay its relatively safe at least.. But still they get no excuse for their fees 
100% agree with you, eBay is safe for buyer. Buyer can play with the seller as he want. If a seller is unlucky and find some scamer, in most of case the seller loosing 3 things; money, goods and reputation (negative feedback)
About fee i don't mind. If i would do google adwords to get customers, the charges would be much higer than the eBay fees...
