They are all over, ebay has them for 15 dollars.
These can be converted to AU's (AP's) with a simple jumper mod, and even set
to 1mhz bandwidth too if need be. They put out 27 dBm which is quite good for
900 mhz. With a small outdoor box you have a nice mast mount AP.
I've attached a system manual on them if you're interested.

I was paying $500 for the commercial version of this, it was about 10dbi at
900mhz. They came in a 4' long 12" PVC pipe radome that accepted a 1.5" pipe
at the end.
Couple this with a M2 17dbi client antenna and you get some nice range.
