So, we tried this:

Works like a charm. Now, we have portable boings. Thats the one I have set up for the smaller birds, we also have one set up for the big guys. These are very stable, my blue and gold had his swinging like mad and it didn't tip at all. Alice played on the little bird one tonight, and tomorrow I'll see what Mazzie thinks of it.
Cheap, easy, and portable play area. Exactly what I like to have available to me! The stands are "cage stands" , bought off ebay, and the boings I buy from the places I trust.
