The $489 at Home Depot model is the way to go, IMO - I have used mine for 20 years (bought it used) and it works as it did on day 1. Sold under Coleman and Black Max names - all are about the same.
220v, single phase, 60 gallon upright, oil-type. Don't buy oilless - for both noise and durability reasons.
