I'm way behind cause I bailed early last night so I could go deer hunting this morning, but wanted to put my 2 cents worth in. I'd like to see you go with the PVC feeder. It's super easy to build, and relatively cheap. The only thing I did differently from what you'll find on the "Show me your feeders" thread is to use 4" PVC instead of 3". I didn't take the parts list to the store when I bought them, and mistakenly bought 4" instead of 3". As it turned out, I'm glad I made the mistake; it holds more feed and is easier to fill (I can use a larger feed scoop). I should have gone with a shorter upright cause I have to stand on tiptoes to fill it, but that's easily rectified.
I hung mine inside a covered run, with the opening facing away from the prevailing wind, and the feeds never gotten wet in the 3-4 months it's been in use.
And there you have my 2 cents worth...enjoy.
