I've been racing/training/riding with a Power Meter (current PowerTap was purchased from Psimet laced to Zipp 404's in fact) for a couple of years. It provides you with a valuable training metric that is not available anywhere else, and Power Meters don't lie. If you want to get better on a bike, it can really help. Not necessary, but good to have if you can afford one, and it can make riding more interesting too.
