The Steam controller is the cheapest new wireless controller at $49.99 coming with its dongle in the box and has the longest battery life by far. The controller works pretty well, but it's got a learning curve and is always going to need a bit of adjusting setting at the start of most games you play at least in the immediate future. If you're not attached to analog sticks and the kind of PC gamer who likes messing with stuff like Sweet FX, ini files, and other settings not usually found in the graphics menu of games than it's worth considering. I'm saying this as someone who bought a Steam controller, but decided to stick to a traditional gamepad instead. I believe in the device, but it's not for me until the software becomes simpler and ideally has a mode where it auto calibrates itself based on a series of questions.
