I just got a Niterider Trail Rat for $100 and it works great. You can spend $250 on the digital evolution, but it's not as bright as the $100 Trail Rat... Burn Time is 2 Hrs and it comes with a slow charger.

It sounds like money is not an object to you however, so I would definately look at the Niterider HID lights at $400! They are the industry standard right now and if you buy from performance, you won't have to worry about anything going wrong with them...
