I have three OpenWRT devices: a Linksys wrt1900ac (v2), and two TP-Link WDR3600s. Considering that you can pick up the WDR3600 on Amazon for roughly $50, it's a steal. I have multiple vlans configured across all three (which OpenWRT makes very easy to do) and certain SSIDs isolated to certain vlans, even on the same radio. I just set up WDS last night between the two WDR3600s, and it was such a simple process. I have the utmost respect for OpenWRT and what it lets you accomplish. Plus, it's far more professionally-run project than other firmwares like Tomato. If you haven't played with OpenWRT yet, I wholeheartedly suggest you do.
