Jan, two months ago I bought a bench from IKEA hoping I could put a couple of cages on it.
The bench is actually beautiful, streamlined, problem is my birds don't like the cages too low (they refuse to go to sleep!) so I had to use it for something else.
If your birds aren't picky about height it could be a good solution
http://www.ikea.com/gb/en/catalog/products/90243297/They have some benches/consoles tthat are higher so maybe more the thing for what you need. They all cost peanuts.
I know you know already... but why buy a Vision? They are a nightmare to clean, birds hate them because they are too shallow.
I have a Vision 2 dismantled and use the pieces for other things like shelves. With the same money on gumtree or ebay you can get a better one.
I know you hate Vision cages so I am surprised!
Anyway back to topic, a wallpaper table will take the weight no problem. I use one myself from Wykes

It bears two cages, flimsy ones but Vision is even lighter so no problem
