Choice of welding carts.  One is Harbor Freight and the other is a Mountain? brand.  The Harbor Freight one fit a Lincoln 140c about perfectly.  The other is about the same size, maybe a slight bit smaller.   Neither fits the new welder very well which is a Lincoln 180.  Width is fine but length is a little shorter than I wanted them.  Harbor freight has front wheels replaced with wider steel casters so I would honestly say it's a little nicer even though it cost about 1/3rd the price of the other one.  Price is for choice, not both of them.
