I use Schlage and Yale (level model and dead bolts), both integrate well. I had issue with Zwave models, so I replaced them with ZigBee and they work much better for me. I know some here also use August. For my wife she did not like the look of August and liked the "Camelot" series look of the Yale
Also know Yale offers a 20% discount if you call them, and ask for it.
