We did our deck with Merbau. Haven't really found any cons (except the price). It looks amazing and we've had the deck up for about two years and have only had to oil it twice. The deck has a roof on it but it does get a fair bit of sun. There are a couple of photos on my Facebook taken on our deck if you want to check it out if that helps. I'm a big fan of the Merbau. But some of the cheaper options can look just as nice or even the same if you get the right colour stain or oil.
