Check your local Craigs List for snake racks. I have purchased two of my racks from there for WAY less then it would have been to buy new or to build my own. One rack even came with a Johnson control.

I'm with you on I have already asked the boys in my life for so much...I can't ask them to build me a snake rack right now. So I'll just resort to buying them.

Animal Plastics also sells an "Economy Rack" for $180 (+ shipping) that includes heat and can fit either 6 32qt tubs or 12 15qt tubs (or a combo of the two sizes). The 15 qt tubs can be found at Target and are $3 each. The 32qt tubs were $5-6 each, also at Target.
