I picked up one for $150. Self catch. Gray. Red handle on chain etc. Forward reverse spring latch plate on top allows it to work in either direction.
Perfect for this little operation at the house in an interim situation. There are never more than a few here. Usually nurse cows or something that needs daily attention. Only 15 acres here.
I'd pay $150 again if I needed one. Heavy duty and it will hold the biggest of bulls. You can't buy the steel and build one yourself for that price. If you need something stronger than a medina for absolute catch isolation, that will do it. I could bring an old squeeze here, but there's no need to do so with that Filson here.
I would not want to work a herd with a unit like that. For what I use it for, it's perfect. Now that I've worked it, I might have paid more.
