I currently own and use a Linksys WRT160N w/ DD-WRT installed. It's running great. No bugs and no bandwidth issues.
I'm a geek and like upgrading my stuff every once in a while. I like to fiddle with 3rd party firmwares, etc.
The Asus is very tempting to buy but it might prove to be an expensive upgrade (200$+tx) for something I do not necessarely need.
Is there any advantages to owning that one over what I already have ? Things I might not be aware of ?
