I saw the wire ones at canadian tire, but I find they tip over easily after using a friends and i didn't feel like spending the money when I had a bunch of scrap materials lying around to make them, all you need is a piece of pvc, some screws, a hacksaw or sawszall, (or better yet a mitre or circ saw if you care about the cuts being straight, i clearly didnt, i might fix it when i feel like going to my garage) , a drill, and a piece of plywood, the thicker the better
only downside i see to these is they're heavier, people carry enough heavy stuff out there as it is and I understand the need for lightweight stuff
