I'm thinking of bringing back to life my original X-Box (it's been collecting dust in the closet). I need to buy some wireless controllers for it.

Which wireless controllers are considered the best? I've seen Logitech ones, but the buttons seemed too close together (particularly to the right thumbstick). Are the Logitech the best ones? You see them on Ebay but they're all refurbs, which leads me to believe that they're not very reliable.

Any advice?

I always used the Logitech wireless controller before I sold off my xbox. It felt a bit weird at first but got used to it. The battery life is great. It'd be my suggestion.

Logitech Precision.

I don't think they made it anymore. MadCatz is probably only ones that still make them - wire and wireless. I tried look for either Microsoft made controller and Logitech, I couldn't find it anywhere.

Only wireless I've used are the Logitech controllers, but they've never had a problem with my Xbox or PS2, so I would recommend them.
