WTB: 5-7 tub ball python rack SoCal

I recently started keeping reptiles as pets again, specifically ball pythons.

I want to start up a collection of them, so I am looking for a heated rack system that holds 5-7 tubs suitable for ball pythons.

I'm open to something home made if you pass on that money savings to me ;) but I do prefer a commercial system, hoping to save some money if I can before resorting to buying new.
