I picked up something similar to this from Northern Tool last year for under $200

All foot activated so handle was removed and forgotten. Don't see it on their website currently but it was much better than that Harbor Freight one I borrowed to try out.

It's similar to what I picked up, just wanted to show that it's all foot-operated and the handle can be completely removed without any hacking\work around needed for ones like the harbor freight model. I don't recommend paying the amazon price for one, just using it for reference.

I do like it and recommend it. As long as you place it properly under the pin, it's not wobbly or likely to slide (mine has a diamond-patterned top to keep it from sliding around) - and when not in use it doesn't take up a ton of space like the wico-type one pictured above. I've been moving several of my pins around lately with it lately (in and out of the 'shop' area) and it makes it very easy.

Only issue I've had was when I lower the pin all the way down - which then I have to crawl under and press the handle a few times to get it high enough to get my leg under it to raise it. Maybe smaller people don't have that issue?? However, it does go down to less than a foot off of the ground if that is indeed what you are looking for.
