Well, its very easy and I can help you out if you need. The only thing you really need to "learn" is wiring heat tape, which is cake. There are videos as well on youtube.

and heres a rack I made over the weekend
If you have the tools, making one is the way to go. Save you a couple hundred dollars or more. And then you can spend that money on some more snakes to fill your new rack!
