I found a used Prince Neos 1000 locally. It looks to be a little rough cosmetically with some paint wear but the seller says it's in good working condition. He bought it from a country club but never used it since his son lost interest. I don't know much about these machines except that they are pretty durable and easy to use. What should I look for as far as things that might be broken or out of spec when I inspect it in person? Do they need to be calibrated? Are there any special parts that should come with it that I should look for to make sure they are included?
