If you decide to go the silver twist route, do not raise the dpad into the cross position. It sounds like a good idea, but it isn't. It will break incredibly fast, and I don't mean wear out. It will literally snap right off. The glue job is terrible.
The best one so far is the silver twist pad, which is the most expensive, and also breaks the easiest. The most durable would be the wired black 360 controller. All of them have an adjustment period, and all of them wear out and break.
