Going with an Aurelia 3 group Auto myself. Around 7-8K installed. Hearing great things about the Aurelia, thermal stability to rival La Marzocco, tons of heating power for beaucoups steam. Frankly though, that argument doesn't hold much for me. A guy down the street uses it and I just ask him when was the last time he had to steam 5 drinks in a 10 minute period. At any rate, the NS Aurelia can keep up there. Oh, and since LM just raised their prices, they are now over 30% higher.
In general however, good luck with any of these. Italy is gone for a month and unless the machine is in stock in the states, you'll be waiting a long long time. Italy is modenizing, but espresso is still traditional, and tradition says take a month off in the summer.
