I really envy the prices in Indonesia, WOW!
Here in Canada, the prices are absolutely crazy, even more expensive than in the States.
Even these tiny little things (that I wouldn't house a mouse in) are expensive.
I like to spend time in the Pet store (just browsing of course

), and It breaks my heart when I see people buying a 12x12x15 inch (or there abouts) cage for a finch, or worse yet, for 2 finches.
Why don't they do their homework about the needs of these creatures that they are taking home with them?
I think people just don't consider, that this is not just their bird's house, it is their whole world, where in most cases they will spend the rest of their life 24/7.

Your picture above, is something like what mine would look like if I put these 4 30x36 inch cages together.
I realize that it's not a problem of the flight cage being too flimsy for the birds themselves, lol.
I worry about it simply collapsing in on itself, or tipping over and collapsing when I do any work on it, or if one of the dogs bumps into the tables these cages are sitting on.
Once you put in perches, it does tend to stabilize things somewhat, but I think it would still need something else to make it more sturdy, or I will have to anchor it to the wall with some small hooks....
