Hi,
Sorry, but don't think you'll get advice from sellers on ebay as you will be the competition!!
One thing you have to be sure of when purchasing from somewhere Far East is that the items are genuine and not cheap tat. I would also steer clear of anything electrical because again a high proportion will be fake and downright dangerous.
