You can't buy product just based on price. How much is the cheaper product going to cost to feed? To get the same amount of nutrients you might be paying more in the long run than going with a costlier product.
Take for instance the SC at 15$ a bag, at 4# per day it will cost you $1.20. A ration balancer like the Enrich 32 at $27 a bag will cost you $.54. With cheaper feeds you might have to add other products as well than no longer make it a more economical choice. If you have horses that do well on just hay and pasture, the addition of concentrates is overkill. The biggest benefit of the concentrates is additional calories that can not be met with just forage. Even cheaper than the balancers is a simple vit/mineral supplement. You can offer it free choice or use it as a top dressing. It will be in a granular form looking like sand. If it's pelletized than you can't offer it free choice because it has added feed products and they will eat it like candy. IMO the best national product out there is the regular Grostrong ($.16/2oz). Another good product is made by Progressive Nutrition. Look for something around 16% Ca, 8% P, 100,000 IU Vit A and less than 20% salt. Purina and MP put out a similar product with much lower levels. You might find your local feed mill puts out a good product that complements your local forages. (they will use it to mix their grain blends).
Don't be fearfull of added fat in a grain concentrate. Fats offer concentrated calories without the risk of digestive disturbances. They can't colic or founder on it, it improves hair and coat, straight fat (oils) are a cheaper source of calories than grains, they help regulate blood glucose....
