I have purchased a pair of Sidi triathalon shoes so I know that I won't have a mountain bike shoe for now. I am going to do some Duathalons in the fall and thought I would start with these shoes. I am a bit compulsive about shoes though so I will probably be adding another pair soon. I will definitely look into the speedplays. My husband uses Looks and it does look like it takes a lot of confidence and strength to unclip.
