I am using OmniGraffle pro. Which is quite fast once you've set up a
set of 'stencils' as they call it.
http://www.omnigroup.com/applications/OmniGraffle/ (Mac only I
believe)
The final results look very good. The program is very flexible and
usable for other creative tasks.
I even managed to do some interior design preparations for my living
room with it.

Greetings,

Ernst
