I found a used superstor selling for about 1/3 the price of new, supposedly only a few years old. The building it was in burned down (at the upper floors), but not in the cellar - but it likely got wet from the firehoses....I haven't seen it yet. Is there anything that can go wrong with these that I should be on the lookout for? Its is superstor 119 model, which is bigger than I would have purchased if new, but these might be a good deal. Would you buy it?
