I made a stand - a play stand rather than a training stand, but just change what you put in the top! - out of a large plastic flower pot and a chopped up secondhand java tree. I put the tree in the pot and filled the pot with postcrete. It was very pretty because it looked like a growing java tree, but it weighed a tonne!!
I'm going to make more as "table top" play stands/perches this year, they'll be the same, but a lot smaller.
You could do the same and just put a T on top not java wood. Before I made that I was looking at getting a mic stand, a hat stand or a lamp and butchering the top into what I wanted.
It's frustrating that the word "bird" or, even worse, "parrot" seems to be code for "usual price x 5"!!!
