I currently have the Pioneer speakers in my truck, and I did purchase them at Wal-Mart... Not sure how much I paid for them, but 60-70 bucks sounds about right. If your not looking for high end, but looking for better/clearer high's then this would probably make for your most cost efficient option... On a 1-10 scale the install is somewhere in the 1-2 range. If I remember right you have to replace the speaker plug on the Pioneers with your stock one... Between that and the removal of the door panel is the only part that some may find difficult. As far as fitment, the speakers fit perfectly. Good luck.
