I use the scan discomobile 2 years. Pros: The mirror is trs fast, colors are vivid and trs there is a choice! Its weight is not excessive.
Inconvnients: Its plastic shell (so far I have not had a problem but the long, I'm afraid!)
It is true that today I had the opportunity to see the new scans turn (other than Martin) in three times less ELC24v/250w Chres trs and really good.
Finally, a great value for scan and trs qualitprix (3-4 years ago in rear)!
