I like the USB rechargeable Moon Gem copies that planet X sells: http://www.planetx.co.uk/i/q/LIAR1ORURRL/areo-10r-(moon-gem)-usb-rechargeable-rear-led-light
Although I see they're doing the actual Moon Gem too.
Not sure if the front is currently available, but I have got it from there in the past.
Good as backups, but I wouldn't want them as a main light.
