RadioPopper has released its new Nano transmitter and receiver units at a low price point of just $69.95 each. With a max range of over 1750′, the Nano sports four channels for dumb slave triggering to a hot shoe or a sync port.
One receiver can trigger two lights simultaneously by using both the hot shoe and sync port. The RadioPopper Nano is also compatible with the RadioPopper RP, PX and JrX units. You can find the RadioPopper Nano here at Adorama.

These would be great if they used standard batteries.
You can pick up a pack of AA batteries anywhere in the world, but these types of batteries are getting harder to find.
