I guess that the moment you step into online sell/buying, you are taking some calculated risks. I've been using Paypal for about 10 years or so and never have a significant issue.
I live in Mexico. Ive been dealing with people in Russian, China,Japan,USA,etc. through ebay and with paypal alone. If you are doing business with someone on the same country, I think bank transfer would work. Otherwise, I will suggest paypal for a more hassle-free transaction.
Just my 2 cents.
