I'm working on an article for budget gaming on the Android platform. I'm trying to decide what sort of wireless controllers to consider. When it comes to controllers, please answer the following questions either yes or no. 1) Price is king. I don't want to spend more than $20 on a controller. 2) I'm willing to pay more for a controller that doesn't require a USB port. 3) I'm willing to consider wireless controllers that require a USB dongle. 4) I already have a PS3 controller I'd be willing to use. 5) If a $30 controller is considerably better built than a $20 controller, I'm willing to spend the extra money. Thanks!
