I've got a 1.2 Eleganza/Emotion with Dualogic and would recommend it to anyone! OK, so I've only had it for ~1500 miles, but no problems so far.
The system's brilliant. It has a semi-auto mode and two full-auto modes, ECO and not-ECO. I keep it in auto+ECO all the time, since the car will still respond to the stick, so right before taking over another car, just pull the lever and it'll drop a gear. I noticed that the car adapts to "hilly areas". Usually it changes gears before 2000RPM, but on a hill (and for some time after) it'll go up to >3000.
I have the hill holder (from VDC/ESP) so it doesn't roll back when driving off on a hill. I don't know what a Dualogic without HH would do.
Note that there have been some revisions to the Dualogic system. I think the current systems are much more reliable than the ones from 2003.
