how to buy with confidence...? PayPal?

you have to take into consideration that getting some people to leave you a feedback score is like pulling teeth even when a transaction goes smooth as silk and they are more than happy with item. about 50% of the people i have done business with has left me feeback, with a 100% satisfaction rate. some dont know how, or are just too lazy to do it (even after i explained to them how). feedback is a great thing, but i dont base my business dealings on it.
