You dont need to spend heaps to get a decent router... admittedly my current smoothwall box is worth about 5 hundy give or take, but at least it's flexible enough to be used for pretty much any PC application (being an EPIA and all) However one of my previous smoothwall boxes cost me a 6 pack of Tui and a small bit of effort. Ran for 6 months solid before a power spike caused its PSU to implode

I had enough spare gear around to replace it with something better
In saying that, having used a Dlink 810+ and a 900+ I'm not overly impressed with them right now, so I've been quietly stocking up on senao and 3com gear
