One more question - transmitter power on these (in the US) is fixed by the FCC, correct? Therefore any differences are due to RAM and CPU and nuanced antenna design?
Buffalo has an "HP" version, which means it has the radio set to max and has a booster antenna. A good (external) antenna can boost as much as 15DBi.
Many models can be upgraded to "alternative" firmware versions, like DD-WRT which lets you boost the transmitter power past the factory setting, sometimes as much as 500% over.
