Are there any other devices or means to measure power at a more economical cost than PowerTap? Thanks.
SEARCH!
iBike Aero is cheaper, and many people claim that it is as accurate as a powertap.
SRM Training System, a torque-measuring crankset that replaces your present modelPowerTap, a torque-measuring hub that you build into a wheelPolar S-710i or CS600, uses a chain vibration sensor that mounts on the right chainstayiBike Pro, a handle-bar mounted power meter that measures the cyclist’s output by measuring opposing forcesQuarq, a torque measuring device that mounts on the crankset spiderBrim Brothers, a force measuring system mounted under the cyclist’s shoePolar are cheaper, as are the iBike. However, not by much.

no, not really.
I’ve seen some wired SL’s going for $400-$500.00 used, and a new Powertap Comp can be had for $650.00.
That’s close to the cost of the ibike, without the many pitfalls (which you can read about elsewhere)
