Cisco BR340's - they're $900/each, and work well in bridge mode. As
someone already stated, make sure you get some good high-gain (and
narrow-beam directional - we use 10 degree yagi) antenna's.

With line of sight, they claim they can go 9+ miles. Of course, weather
does affect it - one of our spans tends to go down when there's just the
right kind of heavy rain.
Theoretic speed is 11Mbit/sec - effective (real) speed is about
6Mbit/sec. (YMMV, that's on a 1/2 mile span)
