I use the Grizzly press. It is the green one at the right in the pic above. I was the original poster in Woodcentral.com when I found it. It was a clearance item. Soon Grizzly sold out all the units.

I mentioned in that post that I had been using a drill stand to assemble pens. For those who don't know, a drill stand is not easy to find anymore. Looks like the base of a drill press, and you put your hand drill on it. I had an old one, from a garage sale. I cut off some of the excess metal on the head, and put it on a base.
After using both the Grizzly and my homebrew contraption, I can say that I like both. Right now my contraption is in the shop, and the Grizzly is inside the house. Nice to be able to assemble pens inside when it gets cold.
