BGK, if your really low on funds for your feeders you could mount them on a tripod, or mount them on shore and use a deer feeder and block 180 degrees of the feeding arc with a piece of plastic. I had to put my feeder on the tripod cause of bear problems.
Here's one on a tripod.
Here's the new feeder I am using, $40., and the bucket comes with the feeder.
