Build one yourself. You can make it cheaper, better, determine the size you want it to be and use any bottle jack you happen to have around. You can just pull the jack out and stick it under a car any time you need it.
The first image is a scan from a '60s HotRod magazine. I didn't build mine until about ten years ago and I kicked myself for not building it sooner.
HotRod's press one two three four I had looked at harbor freight to get some ideas and immediately knew I didn't want theirs. The tables are flimsy and they gave you a couple of plates, but they aren't steel. They are cast iron and easily snap in half. The plates you see on my table are 3/4" and 3/8" for spacing. I had them cut to length with the rest of the pieces when I bought the steel. It was faster, easier and only a few extra bucks to have everything cut. I think the cost for the steel at that time was about $50. The grade 8 bolts and springs I got at OSH. The 5/8" Dia. cold rolled and the angle pieces for the base I had lying around.
I made several changes to the hot rod plans. Mine is 24" wide and 60" tall.
I used less than the four inch spacing on the holes on the side supports, so that I could use two pins on each side if the need arose. Usually I just use the bottom one on each side.
Instead of bolts, I used 5/8" rod between the front and back of the table and welded them in place.
I used 1/2" x 3" steel for the cross bar that the jack sits on instead of the aluminum. The 1 1/2" pin is simply bolted on with a counter sunk 3/8" taper head screw through the top of the plate. The lower 1" pin extension makes it more versatile, but unless you have a lathe, you probably would do well with a one-piece pin like they used.
They welded a ring on the top plate above the jack to keep it centered. I wanted to be able change that a little easier so I bolted that piece of tin on there with a hole in it. The first jack I was using was a 10-ton. When it went south, I got this 12-ton and it had a larger top pad. I simply had to cut the hole larger on the piece of tin. You could probably use an even bigger bottle, but you would need bigger or double up on the springs because of the extra weight.
They show two different methods for holding the side guide bars in place. I used the cable clamps and had to do a lot of grinding and filing on them. The side guide rods have to square with each other so that the plate moves up and down easily. I extended the angle iron for the base only about an inch on the back. I'm not worried about it falling against the wall and I can move it out should I need extra room when pressing something.
