(The site is in Italian)I found a very short clip of it, it stops at the first loop, but hey, it's a start, the site page might take a little while to load, but when it is done, you will see little picture thing under the info of the coaster that will say video, click that and a pop up will open, at the bottom of the pop up, clicka link that says modem 56k (if thats your internet speed) or isdn/ads , I am guess that is cable and dsl. Well, I will continue searching.
