Unfortunately Paypal isn't bulletproof either.
If you happen to have a trojan or keylogger on your computer...nothing is really bulletproof because any form of payment is only as strong as it's password.
Paypal be very very good to me.
Paypal claims their system has never lost a clients money. I had two transactions go bad on ebay (hijacked ebay accounts) and paypal had my money back within 12 days both times.
