I purchased and just recieved my Princeton Corona. It was on Amazon for 46.99 with free shipping. Will use it as a helmet light and I have an old Night rider 15W light that will be in the handle bar. Right out of the box I've been pretty impressed. Good quality construction and it even came with batteries! I played with it in my back yard last night and it throughs a good beam on high. When day light savings is over and I start commuting in the dark I will write again on my thoughts on this light.
