We use George Knight presses, they are american made and great quality.
What we use as well.
However, any of your quality brand presses should do right by you. I wouldn't try to cheap out on a press. Your more economy brands (or even economy models within brand name presses) can cause uneven heat across the platen, which could lead for erratic end products.
We use the geo knights for heat press vinyl, sublimation, print/cut, patch production, applique shapes production. Very good consistent quality. There are others, but really do like geo knight.
