I recently bought this router to replace my old router that finally kaput.  The setup was quick and painless.  I immediately flashed the 3rd part firmware from dd-wrt.com.  That really opened up a lot more options such as the ability to overclock the processor of the router and adjust the transmission power of the wireless radio.  There are many hacks that can be done to this line of routers such as adding an SD card for logs/scripts/etc.  I may try that in the future but my soldering skills suck.  So far it has been rock solid
