Go with something a little bit more reliable. You won't be able to track down that Hong Kong person and give him heck if the part is bad, and you'll just have wasted your time and money. Yes, the ebay guy is more expensive, and smallbear is more expensive still, but at least those people have supplied parts that have been verified by members of this board.
I got mine from Smallbear - expensive, but guaranteed to work.
