Another consideration is what will you be installing at home, if you are not wired down? A "B" router is quite a bit cheaper than a "G", and alot cheaper than a "A/G" mixed. If you are living with others, ask them all to chip in

for a "G" router.
Value, well, "B" is supported everywhere, "G" if available will be faster, assuming your signal is good. Value is a word I generally use to quantify "would I notice a difference in most everyday activities", ie. do I need that Porsche, or is the Honda Civic OK?
