Kept it after I built my bigger pit thinking I would use it for small meals. That was 4 years ago and have only fired it up once. My bigger one really doesn’t use much more fuel, is already set up and is much easier to control so I use it for everything. Absolutely no reason why you shouldn’t build a second pit but really consider if you will use it.
My second build I'm working on now is only 14.5" diameter, and that's 3 x the size of my first one in length!
All depends on what you would use it for I guess. I've outgrown the el cheapo already, but that was more a proof of concept and made from scrap lying around.
