Thank for the reviews.
Sorry it took a few days to respond but I don't get much computer time lately. I will try to answer some of the questions a few of you had.
I too was a little concerned about the humidity, but I will just have to wait and see how it holds up.
The heat tape is stuck right onto the metal beam with silicone.
The tubs were the most expensive item for this rack ($11 each), but I figured they would last for a long time and I can also use them in my Freedom Breeder as well as this home made rack.
As for the router usage:
The bit cut was 1/2" wide so that was fine, but to go the 3/4" deep I had to make 4 passes on each grove on every 2x3. I an effort not to ruin the bit I could only take out 3/16" at a time. This was VERY TIME CONSUMING but the only way I could think of to get it done with the resources available to me.
I thought about the tape up front, but prefer the snakes in the back, especially at feeding time. Some of my snakes still meet me when I slide open the cage at feeding time.
I too like the Freedom Breeder. I also like the caging that I saw at Daytona from ARS. I'm not sure which I will get next. I currently own Freedom Breeder but what I liked about ARS was that it looked like it would be better for retainning humidity, and they also have these magnetic strips which can be added to keep even more of the humidity. I think the were less money that the Freedom Breeder too. Since seeing this I have made some of my own custom pieces to work with my Freedom Breeder and that seems to do fine. I plan on moving and needed something less expensive for now ($520 including 2 more levels to be added). The tubs and heat tape were $360. by themselves. Once I get my new place and see what kind of room I have then I will evaluate what I need.
This rack saved me over $1700. comapared to buying 8 levels from someone else.
Sorry for the long post, but I guess thats what happens when I don't check back here for a few days.
Thanks and happy herping!
