Dualshock 3 is tempting, but I don’t know if I want to spend that much. I would go through USB at first, but would kind of like the option to upgrade to Bluetooth eventually. If this controller is a lot better than the others though (wireless aside) I would strongly consider it.
I ended up choosing to go with 2 official X-Box 360 controllers. Walmart had the official chrome controllers on sale for $35 (and it looks like it’s not hard to find these for around this price, new). It has the “transforming d-pad” and I think the d-pad feels great so far.
I bought the “official” wireless adapter on Amazon for $17 (actually looks like the official MS Chinese product, but still official and works great so far).
It was very easy to set up following the instructions found on this site and the latest versions of everything installed from source.
I would heartily recommend the X-Box 360 controllers (with the transforming d-pad) to anyone trying to decide on a controller.
