If you go with a good higher AC router, you start pushing even closer to $200.

But check out that website, see some reviews. A 3rd ranked in any given AC category router will be solid, but who knows, might be a good bit cheaper.

Wireless N is fine for most people. Might as well get a wireless AC router to be more future proof. If you get that router then buy one used since its $15 shipped.
