I purchased my HItachi CB75F back in 1990. It’s listed on Amazon but says it’s currently unavailable. I’ve seen these used online and I wouldn’t hesitate to buy one. As long as the rubber is on the cast iron wheels, the worst that could happen is that you’d need to put a new motor on it. Other than that it’s so overly built and so robust that not much could go wrong. I also found these new at SamStores.com, but I’ve never dealt with this company.
