I'll add a couple more options to look into:
Koken
http://koken.me/
I think Jamie uses this,he'd be able to give yo some good insight
and 4ormat
http://4ormat.com/
Myself as well as a few other folks in m&a use 4ormat I believe. I'm pretty happy with it overall, only a few gripes, let me know if you want more specifics
