Running heat tape, really isn't that hard. I wouldn't call it serious electrical work its easier then wiring a car stereo system, pretty much any one can do it after reading/watching a video.

There is a lot of videos on YouTube showing you how to wire with soldering or using clamps. I suggest using clamps first time around, unless you are good a soldering and trust your own work. It's worth the work if you know how to properly build your own racks and enjoy building them.
