I've searched and read a few threads on this subject, but none seem to answer my question directly. Basically the situation is that our existing wireless signal does not hit all corners of the house (namely the signal drops off right outside my room). I've looked into a few solutions- the d-link DWL-G800AP wireless range extender, the Netgear powerline wireless range extender WGXB102, or simply buying a couple of the new Buffalo Wireless-G MIMO performance routers and setting one of them up as an access point in the middle of the house.

SInce I am not well versed in the field of wireless networking, what would you say is the better solution?
