I'm not aware of Paypal being a compulsory option. If you don't want to accept Paypal, say so when you are listing your item. For all its foibles, Paypal is still the most efficient way of transferring money over the interwebs.
Fees on sales is standard across any auction establishment, either real or virtual. If you truely think all auctions should be free set up a site and see how long it lasts.
Paypal only charge fees if you register as a professional seller (I seem to remember, I went through this years ago). If you want to accept credit cards, this is a requirement, but not essiential. Again, if you think paypal should be free, the idea of a business model might be strange.
You are not forced to quote a shipping cost, although it's not hard to work out. Mail to and from the YooEss and Europe is one cost, internally is another. Simply weigh your item and work out the costs before you list. It's not rocket science. Then, enter the different costs in your listing.
It seems you are trying to make things as hard as possible for your potential buyers. Lightening up a bit may improve your final sales.
Take care, Ian
