Source for Wireless Bridge

Anyone know a source to buy the wireless bridge? It doesn’t seem to be available from NI or AndyMark. Looking around the web, CompUSA & New Egg have it for $90. Know of anyplace better?

Other than watching auction sites for a used one, then the best I’ve seen is Newegg.

If you don’t need it to be competition legal you could buy a lower cost N or even G adapter, if the router is configured differently, and use that.
