Used AI hydra 52 lights

So was offered to buy three AI 52 lights that are 3 years old don’t believe there the hd ones. He’s wanting $300 each for them. Are used leds something to avoid? I know they have a life span and I’m sure there expensive to have worked on. Just not sure if the savings justifies the lost life or just suck it up and buy new if I go led
Thanks ahead of time
