Stuart posted about the RASKOG cart a while back, saying it was a handy light-duty utility cart for $25. I happened to come across another one, the SUNNERSTA, for $30.
The SUNNERSTA has just two wheels that don’t swivel, whichmight be better or worse, though I’d wonder if they are wobbly. The shelves have a low lip, unlike the RASKOG’s higher walls, and are somewhat bigger. Maybe that would be good for cordless tools. Just looking at it, it appears sturdy enough, though I wonder if it would twist in the vertical direction. But it wouldn’t be hard to attach some diagonal bracing along one side.
I’ll look at it next time I’m there.
