I have the Polly's Perfect Perch and it's great.
I also have a big manzanita play stand similar to the one that Stephanie showed, but I got it at the bird mart and it was a LOT cheaper - about $100 I think. I think the current price is still somewhere in that area, maybe $125. If you're handy with tools and can get hold of an appropriate tree branch, it would be simple and cheap to make your own. Mine is on rollers so it's easy to move around.
If you're still in Seattle they do have a bird expo there, but it's not until October:
