I’d rather a good horse that’ll walk to the river, than have to buy 2 bad horses that will ultimately cost more in the long run 

This is a common olden saying that was said a lot back in the olden days. I think I heard someone say this one time awhile ago. You'd rather have a horse that could walk to the water, than two horse that'll cost me more in the long run.
