The cost of the PVC board over the laminate is crazy. You could build 3 or 4 racks out of Laminate at the same price to build one of the same racks out of the PVC board. Also if you screw up a cut on the laminate it is not that bad, but screw up with the plastic and . Plastic looks nice and is great stuff, but the cost right now does not make it worth it. I would like to fool around with a plastic one eventually, but it just does not come across as something you can play with too much as it is so expensive.

To built a rack the process is the same regardless of the material. Blueapplepaste has a nice rack that probably cost less than $100.00 to make each one. You go to the PVC and you will be looking at about $300.00 to make the same rack.

On another note unless you buy a pro built rack like vision racks or something build the rack that has a solid bottom that the tub sits on and not the type the hang from the upper rails. The solid bottom and top make it much easier to regulate temps. I have built both and I am currently using both. The hanging ones have issues with hitting the flex watt encasement in the back and not always closing very easily. The solid bottom ones slide great. Hanging bottom temps on my Herpstat pro jump between 90.8 and 93.2 degrees. On the solid bottom they go between 91.9 and 92.1 for sweater boxes and my juvies go 91.9 to 92.0.

Below is a picture that has both racks incorporated into it. The 6 on the left of the picture are CB-70's that hang and they are my problem child racks that I will probably change to solid bottoms and tops eventually. The 4 on the right of the incubator are the sweater boxes with solid bottoms and tops. Up top you can see the 12 juvies. This is just my experiences though and you can take it or leave it.



Also to regulate the temps correctly on the CB-70's I had to use a seperate channel for each level. (Total 4 channels or one Herpstat Pro.) For the sweater boxes all 4 are on one channel and the juvies are all on one channel as well.
