Is your arm starting to hurt?
Lloyd, jmatt and I bought our Alexes (Alexi?) at about the same time. We were among the first machines that Chris shipped, so we were "beta testers" of sorts. We all experienced a couple of minor issues that were quickly rectified by Chris. In a couple of cases the problem was caused by UPS (Mine came with water in one of the gauges caused by the box being laid on its side. Chris sent me a new gauge and walked me through changing it and the issue was solved in three days). Another issue was related to the packing and Chris has fixed that for any machines that were shipped after ours. The machine itself is solid, well built and easy to work on if you need to and the service from Chris is fantastic!
As far as performance, I posted this story on the
Alex User Group on Google Groups (A small group of Alex users) but it may help push you over the edge...
Prior to buying my Alex, I had been using an Isomac Millennium. Once Alex arrived I cleaned up the Millennium, emptied the water and set it aside until I found someone to buy it. A gentleman from CG came by to look at the Millennium, so I set it up on the kitchen counter so he could test it. During the conversation, we started talking about bottomless PFs, and I have one on the Alex, so I offered to pull a shot so he and his brother could watch the flow on the bottomless. We had just pulled a couple of shots on the Millennium that he had tasted, so I gave him the Alex shot to taste. He immediately commented on the difference. I had never compared the two, so we pulled another shot on the Millennium and another on the Alex and tasted them. I was amazed at the difference! I knew that the Alex shots were better, but tasting them side-by-side really showed the difference. The Alex shot has a greater depth of flavor and was noticeably sweeter. I used the same coffee (Malabar Gold, two days rest) for both. The Alex was using a bottomless PF while the Isomac was using a stock PF, but I don't think the Bottomless would be responsible for that much difference.
I'm a very happy Alex owner and if i had to make my decision over again I would still buy the Alex.
Good luck with your decision!
