I have the Coffee-Tech Artigiano 2.5Kg shop roaster set up in my basement. As you mentioned, very easy install - I just had to run a couple of 220V lines and vent the exhaust outdoors.
I purchased my unit used, but don't think it had seen a single roast on it - my guess is that it was a conversation piece in the shop I bought it from. The 220V motor on the Cyclone failed very soon after I got it in operation, which after talking to Coffee-Tech, was a known problem with that particular motor. After sending them an International Money Order, they shipped me a new Siemens motor from Israel, and it has been running great since.
Customer Service was very helpful, but required a call to Tel Aviv on my dime and having to have materials shipped Internationally is a pain. The way they packed my new motor was horrible, I had to straighten all the blades on the blower fan as they were all mangled from shipping. They literally put this 20 lb motor and fan in a box and threw a few packing peanuts around it to send it 1/2 way around the world. I couldn't believe it and was none too happy.
Maybe things have gotten better as Dante noted, but I find their build quality to be mediocre. Welds were not very clean, things only line up with a little 'technical tap' at times and the drum inside the machine is, um...not so round.
I do enjoy it now that I got through all the kinks of buying used, and have cranked out 1000+ pounds of coffee out of it and expect it to crank out 1000's more. If I were to do it again, I think I would look for a gas model instead, just for the ease of control.
6 out of 10 would be my rating
