Radiator

Kids were at the cabin and took the ATV’s out yesterday, while turning around on a trail a friend went up an embankment and the ATV went over backwards, he’s OK, and I haven’t seen the ATV yet, but I do know something punctured the radiator. I was looking up what a new radiator for and 850XP online I saw many on ebay for $200 less, they say 30% better cooling but not sure of the quality. Anybody ever use one of these sold on ebay? There are many out there, but I think there all from the same company.
