Those two Asus models aren't too bad. If you don't mind loading DD-WRT, a TP-Link Archer C7 might be the best bang for the buck at $100. If wlan doesn't have to be blazing fast, then an N-class device would also work -- more options to look at there, too. If you're skills are up to snuff, a Mikrotik RB951G-2HND will blow the socks off most anything else at its price point for features. GL!
