To be more helpful, imo it would depend a LOT on the manufacturer. Reputation, quality, etc. If it's a small company� with less exposure and longevity, you don't even know if they will make it long term. A problem could show up in 2 or three years. Will they be around and will they stand behind it? If you don't know the answer to that, then it's an in the moment risk reward question. IF the discount is extreme, I might take a chance on it. But, you would get nothing for it down the road if you ever sold it. If you buy it, be prepared to accept it as write off for resale.
Damaged goods as repaired well is a legit way to get good gear on the cheap, as long as you know you don't get ahead long term. It's best for buy and hold strategy. YMMV
