Lot of 4 HO scale diesel locomotives (rough condition)

Just thought that it would be better to sell these as I don't have the experience needed to repair them, the chessie system F7 doesn't run at all or seem to even pick up power, the Tyco Silver Streak and Santa Fe 4301 do pick up power but don't run, and the life-like Santa Fe 3500 DOES RUN and as far as I know it only needs a bit of lubricant. All locomotives are missing couplers except the front couplers on the F7. If you don't agree with the price I am willing to take offers! I am also open to trade offers if you have any items for HO scale :)
