I love higher power DIY stuff in general, but yea this project really doesnt thrill me. It does sound like the author did adequate research, which is good, but the soldering joints dont inspire a ton of confidence in overall quality. Stuff like this is absolutely what I would consider "worth" paying a professional to do. Especially since buying a retail unit/paying a professional to install it will come with warranties.
