I'm in the market for a 4 tub 32qt rack. I've narrowed it down to these two companies. Can I go wrong with either? Both work out to about the same price (Herp Enclosure rack is on sale for $247 shipped with tubs while RBI is $255 with tubs, both with belly heat). The only real difference is RBI utilizes Iris tubs while HE uses Sterlite tubs.
