Running Firefox with noscript I get nothing but an xml <!--. Everything else is blocked.
My basic opinion, if the site requires me to allow it to run scripts before I see what it is, it isn't worth the time to look at it. I really don't feel it worth the risk to allow anonymous sites to run scripts the moment I visit the site. To many security holes in the OSs today to trust that.
From what you said, PayPal has a lot of people flocking away from it. I left when I had a bad e-bay transaction and they would not help at all. Really showed their colors. Anyway, depending fully on PayPal, you will lose costumers.
