Never send payment western union to someone you don't know. At least with a bank transfer you at least have an account at the other end that you can reference in case of fraud. But I would recommend using an online escrow service. They provide protection for both the buyer and seller. They do charge a fee, but in my opinion its worth it. I found a deal that was too good to be true on this site. He insisted I pay Western Union to a name different than the one on his emails. I suggested using an online escrow service and he called off the deal. Obviously a scam. Be careful.
