Would you mind sharing which brand / model you went with? I spent too much time looking for a more masculine planner last year and finally settled on something that looks like it belongs to a teenager over something that belongs to my wife.
However, they offer fewer layout options in this line than they do in their more popular offerings.
Levenger, as I mentioned, also has some good options, although they are pricey. ARC (I think that's Staples' store brand?) has a line a lot of people buy. Both of these are discbound, which is a choice you either really like or don't.
Filofax & its ilk also have a lot of options that would look fine in a professional setting.
