We have a W M Ironworks crate that works pretty well - you might need someone's help just to make sure the head was correctly lined up before turning them over. I find the crate a real benefit as you can do almost everything - crutching, dagging, vaccinating, foot trimming, checking teeth and udder or testicles, tagging - while you have them captive. The only things I don't use it for are drenching and pour on, which I do in the race. We bought a Modulamb system a couple of years ago and wish we'd done it much sooner.
