Both are in excellent shape,Scanmaster was used about 1 season,and LM-1 used 2 times.Comes with the O2,But it was used with race fuel so I can't guarantee how long it will last!I bought a LC-1 to interface with my powerlogger so don't need the LM-1 which is a stand alone!$150.00 for the Scanmaster,and $150.00 for the LM-1 wideband set up comes with all cables and the bung and plug!See pics.
