My ski boots.
Bought them about ten years ago. They were about £300, I think. They are SO comfy, and exectly right for my skiing. I dread the thought of losing them. Two years ago, I broke the heel plate on one boot. Although they were a discontinued model, I asked the manufacturers if they could repair them. I said that even if repairing them cost more than a new pair of boots, I'd still rather get them repaired. The manufacturers didn't have the parts, because of the range being discontinued. Eventually, I found a ski shop in Italy, who had a stock of the old plates I needed, and they were repaired in Italy. If they ever break again, they're going back to the same place.
