3 underated lenses = very nice kit, what do you think?

I'm in the process of building the "Underrated Kit". I currently own the 40-150 Olympus and planning on adding the Lumix 14 + the 30 Sigma, all of these 3 lenses a bit underated but really very good. These lenses plus my EP L2 and VF3 are going to be my light and travel kit and obviously unexpensive, wich is one important factor for me at the moment.
