the perch supports are closet pole sockets. i picked up a huge box full of them on ebay since buying them one pair per package at walmart for a bunch of cages was not a good option (not to mention that they only carry like 2 pairs at a time). if you are interested you can get some of them here (scroll to the bottom of the page).

i wouldn't necessarily say i did it the easy way but i like it. i cut the bamboo out of a friend's yard, dried it, cut it to size, washed it, sealed it, washed it again and installed it in the cages. took some time but i like it way better than anything else i was using before.
