To add to this, you can make them pretty easy. I have/had one that I made out of 3/4" conduit that is pretty nice. It's been loaned out to a very good friend of mine for a couple years, he offers to bring it back, I've never needed it as I have 4 already so it's pretty well his until I run into a point where I'll need it........ Nah I'll probably just bend another one up.
