Shop Press

It's more about the quality than the tonnage rating, I would guess. I mean, you don't need a powerful press for u-joints -- I do them in my bench vise. Better to have a 6-ton press with good steel than a 20-ton press built cheesily, IMO.

exactly! I have an older one that I bought from another shop that was going out of business..... it is american made and probably from the 60's
