I've been considering the R7000. Most neighbors are likely using $30 Walmart routers so I doubt there's too many $180 routers out there for me to compete with. Do any home wireless routers use the latter technology that you mentioned?
Yes I currently have a 802.11a/g wireless router. Very few of my devices use .11a anymore and most are .11n so it's been time for me to upgrade for awhile. I've always used and preferred .11a for the past 9 years.
