Chessie, I've got both the Bachmann and P2K GP-38's. They are both good engines and the Bachmann, at $35 with DCC was too good to pass up. The detail is pretty good compared to the P2K. The only thing it lacked was drop steps and MU cables. I don't need a sound card for this engine. It sounds like a diesel with no sound card! They both pull about the same but you know when the Bachmann is coming round the bend.
