I don't know if anyone has posted this tip already, but I found a good trick in harvesting wrecks, since a majority of the time you can't get the same weapon twice because they burn up but still show on the scanners that the weapons are there. This burning up of weapons does not apply if the AI shoots the ship

What you do is attack say a junker and make that ship hostile to you in say sigma 13 as an example then park behind the wreck and get him to shoot it while targeting you, this releases the weapons, tractor them in then burn off, its a good way to make a bit of extra cash and also if you want a matching set of lvl 10 weapons etc, the server I play on crashes and resets quite regularly so there is always a respawned wreck somewhere close
