Just bought the 55" AK from USTech. Had my installer, who used to run production at a sign shop, come over to help setup as I've never used a laminator, been sending it out or using Big Squeegee for smaller stuff. She about flipped out because there was no pressure indicators on the dial. I kept telling her to just use the weight of the roller and she kept insisting that it needed additional pressure, thus ruining several pieces (thankfully, of scrap). She said I should send it back. After she left, I played around with it, just let the top roller sit, and after experimenting on several scrap pieces, laminated half of a truck wrap before running out of laminate. Not a problem one. As long as the motor and rollers hold up, I don't see why you would spend $8k.
