Linksys WRT3200ACM is what i recommend. supports openwrt. my 3200 is at my parents being used as an AP only. their router is a Cisco 1921 with zone based firewall and some poe 3750 switches.

My setup here is a Cisco ASA 5512x firewall, catalyst 3750GBe poe switch, WLAN2504 controller and several CAP3702 APs. this requires quite a bit of experience to setup, but works very well. the wlan controller and two APs will probably cost about $300. that alone could be used behind your ISP modem if desired. i’ve got gigabit fiber up/down from ATT and use their modem but pass thru the IP to my asa.

I second this, it's a very capable wifi AP and router that supports openWRT that flashes and installs without any issues (last I tried it about a year ago).
