Go with what you can afford. Corn is everywhere...look for the best prices. Or, if you can, get with a farmer and see if he will sell you some of his corn. We have a friend that sets us up every year...we just went out and found old 55 gal drums to fill up for our feeders for the year. Only bad part about this is that you will have to filter the larger bits of stalk, leaves, etc from the corn so that you don't jam up your feeder if you use a mechanical throw.

I use the cheap scent killer stuff that they sell after the season is over for the following year. Can get it for a heck of alot less than during the season. Then a quick spray before I head out. Works well for me...had them pass by me within 10-15 feet without spooking. Even without brushing!
