Okay, I have been collecting money and doing all sorts of research on building my rack system. I have come to a couple of conclusions: 1. Even my largest Corn doesn't spend much time stretched out. When he IS actually venturing out it is at night. So, if he spends most of his time coiled then he doesn't need as much room as I thought. (I take my snakes out, so they do get some "free time". 2. The total cost of building my own rack with material, sealant/paint, tubs and flexwatt is going to range anywhere between $100 - $200, depending on which plan I go with. 3. I figure it will take me about 4 hours labor to measure, cut wood, draw connection lines and basically build the rack. If I pay myself (or someone else) $10/hour labor that is $40 on top of material. Conclusion??????? I am going to buy a $200 4 tier rack system from Reptile Basics with Flexwatt and tubs provided. SO SUE ME... LOL! At this point, all I need are 4, as I am going to build a long, deep and high enclosure for my Black Rat and may be selling one of my baby female Okeetees. )I can always buy another one to stack later when I have hoarded some money here and there.) The Boaphiles are nice, but more expensive than the Reptile Basics. Animal Plastics doesn't provide the tubs, so they are out of my price range. So, considering all aspects the Reptile Basics is the best value for me. It won't be nearly as heavy as 3/4" melamine or 1/2" plywood, either. I like that. Please feel free to correct any of my flawed logic .
