I probably need to keep it in the 2000 dollar range so I won't get perforated.
Well, that's understandable. If the Outback on 120 volt will work fine, that's what I'd get too. I don't know much about the Magnum Energy inverters, but I guess they're pretty good too. The big Xantrex is best suited to installations where 120/240 volt is needed, in my opinion. And if you don't need that, then the Outback is a better buy.
My bride was the exact opposite. The second time the power went out in the house she about had a conniption. She told me in no uncertain terms to go buy a "decent" inverter no matter what it costs. When I showed her the bill she said it was less than she expected me to spend.
With either one you could do a grid-tie, so that's a new option for you if you buy a new Outback or Xantrex inverter. The Grid-Tie fixes your dump load problems in high winds and such. Although you still have to have a suitable dump load, or automatic turbine/solar shutdown, if the grid fails.
