I don't know how the new Q's are, but the old Dash 200 and 300 were similar in a lot of ways.

I guess the way they started the Dash-8 series was the 100, then the 300, then the 200. They took the 100, took all the kinks out of the 100, then built a stretch version out of that. (ie. the 300) Then they took the 300, put a variation of its engines and all of its guts, for the most part, and crammed it into a 100 shell. So basically, the 200 is a refined 100. The overhead panel, and instrument panel of the 100, 200 and 300 are quite similar. The only noticable difference on the overhead panel is the airconditioning/heat (don't remember the term for it) panel, on the 200 and 300 are different from the 100. On the instrument panel the only thing that comes to mind is there is no Flight/Taxi switch for the spoilers on the 200 and I think 300 as well.

Now as for the Q400, I have never even been in one, so you got me there...

Merry Christmas folks! For the Dash guys/gals, enjoy your time off until the proving runs have been completed and you all get a chance to do IOE. Good luck!
