You should be able to find plenty of used COATS rim clamp tire changers for 1K, or less even. The best part is that these are all USA made machines that are everywhere (typically that’s all you’ll see at tire shops) and you can easily find almost every replacement part you’ll ever need on eBay or you can just call the company. Just make sure to carefully review the specs as some machines will only do up to 18” rims. Also, don’t worry about how a used machine will look. Most tire shops never clean up their machines since they’re so busy using them. A big plastic scraper and a bottle of Goo Gone and most machines clean up quite nicely. I have two COATS machines so let me know if you have any questions.
