I know you have been trying to figure out recently about a new rack system.
The one I recommend on a cheap budget and a great system is the Animal Plastic Rack.
I own one and so many members here. I am actually thinking on getting a 10 shelf one from them this fall.
I recommend checking out the website.

Here is mine with some Snake Guru hooks on the side.
I know they no longer make the tubs he used for this model but I am sure he has alternatives models now for newer model tubs. So shoot him an email. These are great racks that are shipped flat and you build yourself. It takes about 20 minutes to a half hour to build one.
