I can only speak about Gammill. I have had several Gammill's. I had 2 for over 5 years that I rented to the general public. They are still running well! In that time I only lost 1 rental due to a machine problem. That turned out to be something very minor. If I had a little more experience, I wouldn't have lost that rental! I just sold one of them for close to what I paid for it! Gammill makes them in sizes 18, 22, 26, 30 and even 36 inches. For years of trouble free service I'd go with Gammill. As a dealer, for Gammill, I wish I had a dollar for everyone who purchased another brand, and then says....I wish I bought a Gammill! Good luck in your search!
