For long range get more than one of the Asus and set a WDS system (

If One is in a dire need to increase Bandwidth due to the HD Wireless streaming, this might Help (YMMV).

Note: Some people think that having a Dual band Router that provides also 802.11a at 5GHz is a Magic solution to Wireless trouble.
802.11a actually provides less coverage than 802.11g, however since it is working at 5Ghz its Signal to Noise ratio (SNR) is better in some cases than the 802.11g at a specific environment (

If measures show that your 802.11g suffers from disturbing environmental noise then 802.11a might help. Otherwise it is a waste of money to buy Dual Band.
