The PVC works great. I have 3 of them and love them. I got 90 degree elbow, end cap and another short peice of pipe and glud them in an L shape. Then trimmed a hole in the top of the horizontal pipe for them to eat out of. This peice shouldn't be much longer than 16" or else the feed dont gravity flow out to the end cap, thus wasting a pipe that would be any longer. If you search this site correctly there was an old thread on this topic, thats were I got the idea from. Good luck.
