Rack Building?

Who has built a rack system or some sort of multi cage set up? I have 9 snakes currently and it seems that my collection is about to get bigger. In the past Ive bought rack cages but Im fairly handy and looking for a cheaper alternative. Some questions I have are, What materials should I use? where do I buy flex watt? Any other advice that you can think of?

Thanks

I use tim baileys design See it here depending on how you do it they are fairly in expencive I build and wired 5 ten tub racks for less than 500.00.

If you head on over to the Cages and DIY forums, you'll see a lot of wonderful ideas. Usually people will use either expanded PVC or melamine, but some also use metals and other kinds of wood. You can get flexwatt from reptilebasics.com or a few other places as well but most will recommend reptilebasics....
