Just in case anyone has not heard of Marinoni and wants to know what we're talking about ... here's Marinoni's site:

There are three different Ciclos right now ... a Titanium, an Aluminum, and a Steel. When I bought mine, there were only Aluminum and Steel ... so of course I bought the steel one. But looking at the site right now ... that Titanium one is VERY tempting!!
