Just my 2 cents worth.
My have been using a Trendnet TEW-658BRM adsl router for 2 years now with zero issues on a 6meg line. I have the following devices connected with Ethernet: Xbox One, Xbox 360, 2 x Roku, 2 x Mede8er, laptop, Yamaha rx-v475. Wireless I have 3 devices connected, Sony Xperia, Samsung S2, Samsung Note.
I use UnoTelly for Netflix US, BBC iPlayer, 4OD, Demand 5, SkyNews, BBC News, BBC Sport, and a couple others on the Roku. I also use Rdio on my wireless devices for music.
You can pick them up for cheap, probably R500 to R600. It supports static routes, but I prefer to actually totally block the public DNS ip's directly on the routers firewall to fix the Roku Netflix issue. So if you can't afford an expensive router, have a look at the TrendNet. Cheap, but functional.
