i think personally, the best idea is to ship to your sister, collection only, or she could post by a tracked courier, only payment via paypal, i think you should be fine.
i've had problems with ebay but it has just been people selling me shit without mentioning the problems.
edit: and it all worked out for me in the end.
never had any problems selling, if you describe the item accurately, and ship tracked, you're golden
