im going to use a helix thermostat and flexwatt heat tape for the belly heat and that should keep them nice and cozy. yea i was thinking about it some more (im at work so bored haha) and i decided im just going to go with melamine because like you said it is only 5 tubs so it wont be too bad. thanks for the idea of the casters it will make moving it that much easier and i will definitely post some pics of the rack when im done with it and ill include some pics of my pride and joy wait i mean my prideS and joyS
