MidWest used to manufacture the box blades (and some other implements) sold by First Choice. These implements generally received great reviews here on TBN. For some reason, First Choice and Midwest had a parting of the ways, so you can no longer get Midwest implements from First Choice.
I assume JimMc will be getting some dealers to sign on selling Midwest implements very soon. I know he has an arrangement with Kioti now, but he told me he will be selling the Midwest line as well through dealers.
