If your going to spend the money, go with the dual band (A/B/G). Most likely the 11A standard isnt' going to last much longer. A and B were the orignal standard. A got 54MBps but had reduced range, B got 11MBps (a standard Cable/DSL connection will use about 5% of that) but had better range. 11G basically is combining the 54MBps and range/frequency of 11B. I don't think the final draft of the standard is out yet though, so it may not be entirely stable. I run just a straight 11B network with a D-Link router and I'm happy. If I need to transfer a huge amount of files, I just hardwire into the router and get the 100MBps Cat5e offers.
