They do come in smaller slider - the SCM's online brochure only have them available in 3.2m, but they are available in 2.2m, 3.2m and 3.8m.
Again, SCM's website/info on their machines are very limited especially the L'Invincibile line - there is less information on SCM website compare to their Class/Nova/Minimax range - You'd think you're spending more money there should be more info, but NO..... in some instance you get more information from second hand dealer who try to sell them.
I have seen the L'Invincibile saw in person when I visited SCM a while back (also bump into a guy who runs a business with almost everything in L'Invincibile), I know what to expect, the good and the bad.
