By sheer stroke of fortune I have managed to sample the EX-1, EX-2 and MT-s. Firstly I must say all 3 seemed much better than my DX3r pro, especially the trigger, but I was mighty impressed by the ko propo quality.
The EX-1 didn't have the 3D extension but felt nice in the hand and not as heavy as i first though. Although I liked the EX-2 and its lightness, I must admit I didnt like the english/japanese (or chinese) menu. Not sure there is a software upgrade to only have english in the menu system?
I had previously tested the M12 and felt the balance was ok but build quality was poor for that price range.
I have therefor taken the plunge and ordered a EX-1 (found a nice offer online). Will keep everyone posted with pictures once I have it. Will order the 3D drop down and need to order a extra RX for VRC Pro - would the KR211 do?
Update: you'll be the first to know if this was a massive regret
