If the seller is reputed, I believe you will be in safe hands. Like in Subransu's case, he got his money back as the seller was not a Scammer. However, irrespective of what you buy, if the seller is a fraud like this one, he will ensure to keep the money and never ship anything. He knows how to fool paisapay to collect the money (in his own words).
So the underline fact is we need to buy only from reputed seller (especially power sellers) as ebay is too inefficient in protecting us from scammers who register on ebay, take your money and run away making a mockery of the entire process of 100% guarantee.
