I finished my second "mod" of a trademark 600 chip birdcage, creating a space underneath four racks of chips to hold cards, dealer buttons, seating chips, and change for cash games. I have to use the cheaper brybelly racks if I want them to fit, but it works out ok. I'm not sure I would trust the handles with 200 more chips. The two cages I've worked with have slightly different dimensions, but I made them both work. One has a felt lining, the other doesn't.
