I'm not a paypal booster, by any means. I feel it only fair to mention that most of the warnings on www.paypalsucks.com
were posted before the takeover by eBay.
I have my own horror story with them. Before eBay took them over, apparently they were using prison labor to run their computers. This is a more common practice than you might imagine. I signed up for a PayPal account, and two weeks later, eBay caught someone using my credit card number to register as a seller on eBay.
I cancelled the card, and got a new one before anything untoward happened. I was really leery about setting up a paypal account after that, until eBay purchased PayPal
I haven't had any problems with PayPal since eBay purchased them. But you need to use some common sense. Credit card companies are very reluctant to settle accounts unless there is real fraud involved. So going through them doesn't make much difference, either. Let those feedback ratings guide you.
And don't buy anything from Singapore or Indonesia. There are a number of sellers in both these countries that are notorious for lifting photos from other people's sales and/or web sites and listing the items as their own.
A friend of mine in the banjo business spotted one of his photos on eBay. The idiot who used it simply had a direct link to Dave's site. So Dave modified the photo on his site so it had "This photo stolen from XXXXX Banjo Shop. Seller does not have this item" superimposed on it. That kind of bit into the seller's bids!
