Markus,
There are no hard and fast rules really. All trades are done at your own risk, but... The great thing about this forum is that it is very open, friendly, and honest. If you are unsure about a trader, or want opinions, just ask. No one will get offended if you ask about the 'validity' of a seller. That's the very thing that keeps this place honest.

Payments tend to be bank transfers, PayPal or meet up in person. PayPal seems to be fairly common, as it does offer protection.
Most sellers offer international insured shipping.
