Folding Saw horse opinions
The best I ever came across was by Fulton and called Tote a Horse; though not cheap. They are just like the yellow Crawfords mentioned, except they were the original, and none of the knock offs can come close to them for durability. I have two sets that are over 12 years old and one of them is just starting to get a little sloppy. I'm not sure if they are still available or if driven out of the market by the cheap knock offs.
I also have several of the yellow HD ones. When they first appeared, they were pretty good(actually excellent for the price). I would get a couple of years from them, then they would be relagated to holding finish wood for priming when the legs got too sloppy for me, and eventually would get sent to the dumpster. Even though the price is still right, the last set I bought was pure junk. The metal has gotten so poor that the pivot bolts had almost worn through the metal in a couple of months. Thinking that I will try the Trojans next, like the versatilty of using any length and depth 2 by for the tops.
