ok so wireless n is finally arriving. should i buy it or should i wait a few weeks? there are 4 to choose from. netgear linksys buffalo and belkin. 3 of them are priced at ~130-150. the netgear, is 220. why is that? it is called the gigabit edition. is that because it can move wired net at 1 gigabit? i am looking to purchase it because i got caught up in the belkin pre n scam which is just b and g combined. thanks in advance for any info
