Vouch for Gerrod. I've sold this guy a few billion gp over time via direct Paypal. Never had any issues and he always comes through. One of the few people I would accept direct paypal from.
Vouch for thepker3, have sold him well over 600M RSGP in the past few months. Love trading with him. He's such a nice guy and I absolutely have no hesitancy accepting direct PayPal from him.
