For home use; if you need 220v it's not available unless you step up to the 6000w models, which are very pricey $3k+, and not very portable. At that point you start to push into the cost range of much larger home standby gens that would handle the whole house including central air and electric cooking. The difference being that the home standby units will run another few $k for installation, but the back side of that is it would significantly improve the home value and marketability. Most generators of either type can be adapted to run on LP or natural gas so you don't have keep messing with stale fuel or supply issues (following Sandy, the gasoline shortages were a big issue in NY metro, and the same would happen if there were a big ice storm).

So your best choices IMHO come down to the under $1k small inverters and contractors-type (noisy) portable units or make the big leap to a permanent installation that runs on LP or (even better if you have it) natural gas.
