BGuard,
There is one other brand around, a company out of Mississippi called Navigator. Not as well known as Moffitt or Princeton but my experience with them is that they are quite structurally sound (especially in the mast traverse system and easy to adjust), parts are commonly available, price competitive, company was very responsive to customer issues (seemed to do what is right for customer satisfaction). Plus, the trailer mounting kit is less expensive, similar to the Teledyne Princeton system (always ask how much it is & an estimate for the installation cost). They have a web site.
Had a customer in 2002 when I sold them, they were in the sod business & they tried them all, except (Manitou) and kept coming back for more Navigators & still do. Units held up well in the lumber business.
There are two other brands called "Donkey" & "Grass Hopper". I would not recommend them but to each their own.
From three you identified Moffit would be my second choice.
I am retired from the lift truck business now - just sharing some of my experiences.
