Actually, the most secure (for seller) AND FASTEST payment is direct deposit to the bank account of the seller. As far as I know, buyer and seller must use the same bank for this to work, but maybe not. The negative for the seller is that he must give the buyer his (the seller's) bank account number. However, the seller may employ the same two bank account strategy that some sellers do with Paypal payments, only here there is no charge back mechanism (as there is with Paypal).
As a buyer I used cashier's checks from Bank of America, which had a very seller friendly feature. On the back of the check was an 800 number that the seller could call to verify the authenticity of the check. Later he could call to confirm that the check had been paid.
