Hey guys. I'm looking at buying a rapid-fire kit for my wireless xbox 360 controller. I have been looking at several being sold on ebay, and it's so hard to choose! Being my first rapid-fire kit, I have no idea what to look for or what is generally preferred. Many kits that I see advertise as being "4 mode" and such, and some state that they have a potentiometer to allow you to customize the rate of fire to your liking. However, I have no idea if I need "burst mode", or what I should look for in a kit, generally speaking. I will show you the links of a few that I am looking at buying; hopefully someone can check them out for me and offer some feedback so that I can make a good, informed buying decision!
