TimA: I have had good runs with TP Link, The most reliable pile of $75 i have ever spent in network gear. My little Wireless N 2.4 and 5ghz AP out performs my HG659 and beat my last Cisco.I have to second this, I have 5 dirt cheap TP Link APs, and while being nothing flash they HAVE been reliable. They were purchased with 'why do we need wifi at all' from management.. so price was the driving factor. But they have stood up when it comes to reliability.
sbiddle: The biggest problem with Unifi's is the lack of any band steering to 5Ghz. Having to run multiple SSIDs to use 5Ghz is just a total pain.
That is *supposed* to be coming. It may not be as fast as I'd like but UBNT does add features to it's products. UBNT would be by goto for wifi now, a really good combination of price/performance.
