$110 refurbished http://slickdeals.net/f/6807794-asus-rt-ac66u-dual-band-wireles "Yes, it works fine with DD-WRT. But if you end up buying, I would recommend trying just the stock firmware, or Merlin. I had an older Asus router running DD-WRT for years and when I got this, updated to latest version of Merlin and have been very happy with it, both in terms of features and performance. Merlin can be installed using the built-in firmware update feature - much easier than flashing DD-WRT. "
