Yeah, I use them all the time without problems. The trick to that is being sure I can probably trust the person on the other end. I reduce risk where possible, esp with reputation tools.
Of course not everybody has problems with PayPal. If they did, PayPal would have been dead by now. But there have been way too many cases where PayPal clearly took money that wasn't theirs, and thereby endangered business and customer interests. Even one such case should be enough to disqualify them as payment provider. It is not their money. They should just enable the transaction.
