After researching all the diffrent options i decided that a mixer was the best way to go for listing to the mp3 player and radar why'll riding. My question is where can i get a mixer? i only need 2 inputs for the mp3 player and radar and one output for the headphones.

If your lost to what i'm talking about its one of these, i'm just hoping to find somthing for half the cost.
