I'll second the stur-d, we bought one this fall and there extremely sturdy as the name implies, we have had crazy cows that you can't hold in panels but the stur-d tub held them no matter how hard or high they jumped, the tub is one solid unit so it isn't going to break like I have seen others do. If you decide to buy one I would really recomend the stur-d. I also like the adjustible alley, if you are working calves one day and cows the next all you have to do is lift 4 bars and push in. The head gate isnt to bad either, it was a little stiff when we got it but after runinng about 150 head through it, it loosened up so it works pretty good, the only negative comment I have is that when your branding shoulder branding yearlings it can be a little hard to get at the shoulder.
