The model 32 is built stronger than the 3 & 4. I know a guy that has a 4 and he borrowed my die from the 32, and everything about the 32 was bigger so he couldn't use it. You can spend the extra $400+ and get the hydraulics for the 32. The new one that's replacing the model 4 is going to be top notch. The biggest I've bent with mine is 2 1/8 x .188 DOM. It's a workout bending that manually.
