I've been waiting for a year and hoping a few reputable, service capable dealers in the U.S. will take on the new air cooled Carette. It is priced to compete with Omegas but seems to be much more of a robust design.
For guys who don't want to step up to the Alkin weight class (145 lbs) and price class ($3200) there is the Coltri MCH-6 which is 100 lbs. and $2700. Below that price point it's risky business. It is sad to see the guys who take small steps up the compressor price ladder after each compressor failure. I know several of them. When they add up their losses the Alkin seems cheap in comparison to a collection of dead compressors.
