Does anyone know if the Power Cranks work to improve your pedaling stroke? Are they worth the big$$? Does anyone have a used Power Crank they would like to sale?

NC roadie - are you talking about those made-in-Scandinavia pedals (not cranks) that allow one direction of rotation, but lock up in the opposite direction? I used to train with a rider who rode with them for a few weeks. He thought they did nothing for him. He also complained about the weight. They were, in fact, very heavy.

If there are power cranks (not pedals), I know nothing about those.

Is that the one with the little cam that advances and retards the crank arms at different parts of the pedal stroke? If so, it just seems to me to be an expensive, complicated and heavy way to do the same thing as a bio-pace chainring.

Every few years, another miracle product is unleashed on the cycling community to great ballyhoo and a flood of press releases. Many in the cycling press fall for such clap trap over and over again. Each one is said to save X% of energy, improve performance, prolong life, etc. The tag line on their ads should read "Power Cranks, because you'll believe anything!" Save this message and insert the next great innovation when it comes along. Please note how well these are selling (AKA not at all). Sorry for my harsh and skeptical attitude, but NOT ONE of these things has actually worked in the 35 years I've been cycling. Even the marketing might of Shimano couldn't make BioPace work.
