Check out ModernBikes.com. I bought two MiNewt 600's over the course of four weeks. Paid $102 and $105. I ride on dark, country roads. The 600 mounted on the handlebars I run on medium. The 600 on the helmet I run on high. Excellent light. Includes a helmet mount. Wrapped some tape around the handlebar(a rubber spacer would work) and mounted the light--no problems. It's brighter than my old Magicshine 900.
