No experience but wow, they've increased significantly. I don't see a problem if it is from the same manufacturer but I also don't see a way to confirm that. That being said, I would probably purchase from a reputable supplier rather than Ebay in the event of an issue. Not sure if you're aware but there is also a heat shield sleeve that covers the braided part behind the engine. I replaced both.
That eBay oil line looks a lot like the aftermarket one made by Cohline. I just bought a Cohline one for my car, and was pleased with the quality. As Vegas993 suggested, be sure to get a new insulating wrap while you're at it.
Some people have had luck with having the flexible section of the original replaced at a local hydraulics shop, but when I checked around here, the cost was more than buying a whole new one.
Good luck,
