Park Tool PW-3 Pedal Wrench
Ideal for home or shop use, this pedal wrench is built to last. Investment cast steel construction is reinforced at high stress areas. Unlike most flat pedal wrenches, the long, vinyl dipped handle provides a comfortable grip and plenty of torque.
With the price difference being so small, you'd really do well to go for Park's more ergo offering: http://www.pricepoint.com/Brand/Park-Tool/Park-Tool-PW-4-Professional-Pedal-Wrench.axd
