Very new with all of this, but I have a sparkfun Pan/tilt kit, I would like to have a 4 axis joystick ( pan right -pan left- pan up -pan down) I can only find 2 axis joy stick. Would I be better off to use a 4 button pad of some kind? And if so any ideas?

Sorry, not negative vs positive, usually resting position is in the middle of the value range for that axis. So for a lot of analog joysticks, it's just two potentiometers with values from 0 to 1024, with the middle position being 512. Don't know what I was thinking with negative values.
