We stick our 250lb tubs in a big truck/semi-tire. The local tire guys will give them away if they can't repair them. When they are empty, we cut the sides of the tub down to about 8-10 inches with and use them for grain feeders for the project steers or whatever. We pay $79 for a 250lb. tub @ 17% protein. I believe the lower protein ones are a few bucks cheaper.
