The general consensus is that the Dynorad is worth the extra money. I prefer a stopwatch myself, as the HP figures from any of these won't be accurate, they are mostly useful for before and after comparisons.

maybe I'm still trying to calculate my weight. I know how, now, but haven't. I also don't wanna burn the fuel up "testing."

-retarded, I know. No flames.

What can I help you with, sir?
