What's your outdoor set up - covered patio, screened in porch, totally uncovered? I use thrift store finds & run them til they give out. Too lazy to move stuff in & out so the cheap stuff stays outside. Small receiver, cheap DVD player for CD's & some Advent 3002's & it's all good. Total cost under $30.
BTW, I have a covered patio so the gear is protected from rain. I live in Mississippi so the gear is exposed to high humidity & heat, but almost no freezing conditions. The main stuff I deal with is dust, pollen & spiders.
