Idaho hunter 58, just curious as to what your hunting area is like, and how much of an area you have to hunt. Are bear densities high? What is hunting pressure like? If you are in a relatively secluded area with a lot of bears (and not too many other hunters/baits) you will likely need a lot of bait to allow your bait station to reach its potential. Grain (oats) mixed with used fryer/cooking oil works good and is cheap. Meat scraps work well and beaver carcasses might be a bear's favorite food.

If bear densities aren't that high and there is major competition (other hunters/baits) in the area, use as many different things as you can and you should find out what works best in your area. The more competition there is, the more important it is to use the most attractive type of bait. The less competition and higher the bear densities, the more important it is to use more bait to keep as many bears coming back as you can- thus increasing ur chances of the big bears being around.
