I have us3d Paypal extensively for all the reasons mentioned already: ease of use; international payments; security.

I would emphasise the people are aware of "phishing" emails spoof ones seeking your account. In fact because I buy and sell with regularity I never take any money out - just use it for purchases and so on.

Recommended by me and undoubtedly better since Ebay took over. However for an alternative view see:
