i too haven't heard negative feedback on Niterider. A lot of my friends use various types (including the HID) and are happy with all of them.

i use a very low cost Insight from Planet Bike, which was about 130$ canadian. i have three settings 9, 12, and 15W. 15 watts runs for about 1:30 ish. for the price, i do like it a lot, but the bulb isn't quite as bright as i would like but its all i could afford

night riding is A LOT OF FUN though. enjoy!
