We have acquired a few lights via Ebay and have not experienced any problems. Everyone else has covered the main things well.
Something we do is keep track of who we purchased the lights from. We know who we have done business with before and that helps
with the comfort/confidence level. Since the 6 lights we still need are all in the $400 and up range, we hope to acquire them from someone we have already done business with.
