I like mine that are built out of sucker rod and haven't had one break but they have been bent up but still in service long after the square tubing ones break and fall apart.Just nobody sells them and I don't have the wont to build them. If I had a set up like Blue River I may
I have looked at the black poly ones $270 but I seen that the bolts could eventually pull threw(need bigger washers at least),where they are fused together could break and no way to heat them back together unless have a poly fusing machine and light weight.We have a pile of the square tubing ones,i need to go threw and weld ones can save back together. I just bought 4 new ones,the green ones at TSC with my 10%off coupon. I also drove and picked up some of the 10' concrete troughs and stopped messing with those plastic ones,first cow steps into bust a hole in,$140pc and weigh 2,000lbs so no cows going to slide them around either.
