Which model are you interested in? We have just replaced Drytac JM SHA with JM Fusion.
SHA is basic model and it is ok for shorter runs … tracking of long prints can be PITA. It is designed more for photographers or frame shops than for sign shops. Only problem we had was replacement of 2A Circuit Breaker with 4A.
I wouldn’t recommend older models than SHA as i think they have two handles for lowering the roller. I have no experience on older models but i just can’t imagine how can you obtain equal pressure on both sides.
Fusion seems like the real deal for our needs … so far we are satisfied.
