I already know how it is because i'm in the process of doing it myself. It's really not that hard if you have access to the things you need. Really, all it takes is a little bit of brain power and time. To me it's worth not spending the extra grand. Besides, by doing it yourself, you can have the inlet(s), outlet, and everything else right where you wan't it. I guess I just like to have things diffrent from everyone else.
