I'm the Western North Carolina dealer for Hud-Son Forest Equipment. 23 have mills ranging from up to 21" and up. It all depends on your needs. Hud-Son Sawmill USA Portable Sawmills that's the website. Let me know if you have any more specific questions. Where are you located? I'll be doing 5 days of demonstration at the Southeast Old Threshers Reunion in Denton, NC this weekend. If that's not to far for you, come on by and see some logs turned into lumber.
