If you truly want an idiot-friendly skimmer that is high performance, then I would get a Euroreef. The only thing to adjust is the height of the water inside the skimmer, by sliding the output tube up and down. This thing has pulled out more gunk in 2 weeks that my reef devil did in 2 months. They seem expensive at first, but they include a pump with a lifetime waranty.
For a 120, the CS6-1 would be a great choice. Jeff's Exotic fish has it for $269, which includes the aspirating pump. I pulled mine out of the box, placed it in my sump and had it running in 10 minutes. The only drawback is that they require a lot of room in your sump. HTH.
