They have taken the Oz market by storm because they are lighter, brighter and easier to mount than nearly anything around. Weighs quite a bit less than the MinNewt but throws out 320lumens+. (MiNewt 110+)

I have used them on the road (one set) and MTB (helmet and handlebars) and wouldn't use anything else. Plus they come in damned pretty colours, which is always important!

They have quite a good export market in the USA - and the dollar is probably looking after you at the moment compared to ours, so that may bring the price to somewhere reasonable. Not sure on the pricing relative to the NiteRider products in the USA, but here in Oz it is the best bang for your buck that you can buy.
