Single Mi-newt here (first-generation), and very happy with it. The first-gens were not as bright as the new MiNewt.X2. The MiNewt.X2 packs an incredible amount of light into a very small package.

Also, last time I checked (several weeks ago), QBP and Seattle Bike Supply both distributed NiteRider products, so any LBS with a QBP or SBS account should be able to order them for you.
