I spent years with a bench press I got from Dayton, I think it was. Looking back, I have to be amazed at some of the work that was done with it. I wouldn't be put off by size, but in the long run, bigger is better.
More important than size is the versatility of the table, the ability to crank up and down, and rotate. Just as important as the press itself, however, are the accessories (vises). To my way of thinking, they really make the press a tool. By the time you get something that has X-Y movement and tilt (oh, sorry, you have that in your table), you're talking an extra couple hundred bucks, so figure that into the deal.
Floor models. I like to have the table up fairly close to my eyes, so that's going to be about 42-48" off the floor. From what I've seen in the past few years, most of the floor units are made for really, very, awfully short people. I dunno. Maybe they sell extensions. Maybe someone else can comment on this.
