Don't even hesitate to use Skype. One of the most reliable for video chatting and free long distance, who doesn't love that. I've enjoyed their service immensely.
If you want your account frozen and they keep your money until who knows when and be talked down to and be treated like you-re a nobody, then paypal is the place for you!
~Stay away, paypal is a joke as there are much better payment sites out there. This is the reason ebay loses so many people, paypal is so poorly run. This has been my experience with them.
They were good to order parts through and were very knowledgable on what I needed. The part went in easy enough and the camera hasn't missed a beat since. They gave great service and advice and I recommend them highly.
