We are currently building a new home that is single storey and around 3000sqft. I was looking into Ubiquiti Nano HD but I am able to get second hand 2 x R600 with PoE injectors for US$315 in my country from a IT distributor that comes with 1 year warranty. The condition of the R600 is excellent. Is this a good deal for 2 units and from your experience will this cover a 3000sqft house with timber framing? I plan to use it with unleashed firmware. Is wave 2 really a game changer that R600 does not have being an older model? Thanks.
