I'm pretty sure the 8mm isn't included here; it's not listed on the website, but more than that a friend of mine bought one a few months ago. His definitely didn't come with an 8mm collet - I had to give him mine (that I'd never used in the 5+ years I'd had my 1400) when he bought some Festool 8mm cutters.
I've used 1400 on laminate and solid worktops for at least 5/6 years with no problems.
Dust collection is not great though better on 2200 I expect, but couldn't stretch to 2200 at the time.
I do like the handle setup on the 1400 and it's much lighter than the 2200.
