This cost me $30AU download, and the difference in ease of placement is incredible.
It is the actual tool used by the FTX scenery builders. So far I am extremely happy with it.
After spending days nudging objects around in SAMM2, restarting FSX, checking the latest error, closing, opening SAMM2, tweaking, etc ad nauseum,
I repositioned everything and added more in an hour or so, including finding extra on line aircraft and installing into FSX.
I'll come back in a couple of minutes with an edit......
EDIT
This is FSX (duh!)

This is Google Earth
