The Omegas as well as AV and now Hatsan all seem like good compressors. I am still weighing options but will probably break down and spend the money for an Airetex. Seems to have dive quality build, long period till first recommended rebuild, and an apparently superior drying system. Expensive and 220V but seems like it would be foolproof. Still, any mechanical unit can have problems.
...the repair parts are easily ordered from the PA website.
