I certainly agree that there is no substitute for cone wrenches but I've found several pedals have wrench flats wide enough to accept a standard 15 mm combination wrench. My Speedplay Frogs, Shimano M535 SPDs and an old pair of SR quill pedals can all be installed/removed with an ordinary Craftsman 15 mm combination wrench. Other models do require the special thinner pedal wrench. Upshot; check your particular pedals before buying a specialty wrench.
