Most all-in-ones have all equipment including lights (choose a higher end light) pump, skimmer, heater, canopy, total 30 gallons, for around 300.00. You can resell those if you like the hobby. They do fine with a couple of clowns and a bubble tip anemone, and they also do nicely with a couple or 3 goby or blenny types (they get along) and some zoas or mushrooms. You still have the ato issue. But the canopy helps slow down evaporation, which is not important to softie corals or anemones. (It is, to stony coral.) Hope that helps.
