I have an Express/Emphasis system, and while I think it's a great console(s), one thing it doesn't do very well is control Movers, even with Emphasis. IMO Expression is only a bit better then Express and I would not at this date recommend either if you want easy ML control - Sorry to Sarah and all the great folks at ETC, for that comment.
The bottom line as of today, is both Expression/Insight and Express consoles are dated controllers with ancient hardware (the single biggest issue with the consoles currently) and I suspect that once Ion gets really rolling and ETC comes out with a console between Ion and Eos, that ETC will discontinue first the Expression/Insight followed by the Express.
That said, the Smartfade and Smartfade ML are very good replacements in the lower end of the line, with Ion at the middle and both are the ETC controllers to consider, as both are reasonably good at ML - or so all the street buzz is telling us.

I secnond everything Serra said in regards to this post and add my own two cents...
The Hog 2 is a "dated controller with ancient hardware" but its still being put to constant use. The 3 of them are good boards and you won't see the end of them for some time to come still...hell High end/flying pig couldn't get rid of the Hog 2 with the Hog 3
As for Ion/Eos....I tend to shy away from boards that seem like they have flashy graphics to have flashy graphics....why are we eating up proscessor power so my palletes can slide on to the screen?
