in case you didnt know you are looking at about $2000 for a quarq setup, and $2300 for a SRM set up. Ergomo is out of business I think so don't even consider that. A midrange powertap is about $1000. You can get the competitive cyclist wired powertap deal for $659.
Pick up training and racing with a powermeter and read it before you buy a powermeter to see what your getting yourself into.
