I was in one of our two local Lowes stores this afternoon to pick up some plumbing supplies. I was looking for elbows when I saw these things:
LASCO PVC Fittings I bought eight of the 3/4-inch 3-way elbows, for about a $1 each, so I can build a new fish cage at the end of the dock.
They had them in 1/2-inch, 3/4-inch, and 1-inch. I asked one of the plumbing helpers when they started stocking these things -- she said they always have them! I guess I've been blind in all my trips to their plumbing department.
