Glad you like the rack man, I know I'm really happy with mine. You think the ventilation in the tubs is enough? I'm still debating whether to drill holes or not. I don't really want to because I don't want to lose heat, so far my frogs haven't showed any signs of distress and it's been about a month. You could always look for an old TV stand or something as a shelf, maybe check local junky antique malls or something for a decent stand/table. I use some kind of old wooden shelf my dad had laying around.. he collects antiques and junk, I think the shelf looks pretty good. The shelf I'm using comes up to my waist which is perfect.
