Stihl 031 & Mac super pro 81 values

[[email protected]]

Since I have finally gotten smart enough to move where I don't have to cut cords of firewood every winter and I'm destashing my tools to buy new woodworking tools, I have a Stihl 032 and Mac Super Pro 81 to sell. They both are in good condition and run well. Can anyone give me an approximate value for them.
thanks for the help,
