Power Meters / Powermeters (SRM, Powertap, Quarq, Ergomo, Vector, Stages, power2max, P2M, 4iii, InPower, Cinch)

The 'Stages' system looks nice. Such a shame they dont do Rotor arms. Would be amazing if you could just send off your own left crank arm, and have it modified. But I guess there's all sorts of issues with that idea.

Found a slightly better price for the power2max. Plus a nice selection of other power goodies.

Chung (who did the testing with DC Rainmaker) said on wattage that the PowerCal is better than the Stages.
