I've moved from Cartographer to Mapster.
I preferred Cartographer, but CK Knight has posted he will not update it.

The Cartographer map was about an inch off (to the left) of the actual map.
Although the x,y coordinates were still spot on, for actual position.

With Mapster, the map is in sync, with the actual wow map.
I have the QH points, off on the world map, but still use the arrow in play.
And then go with the blizzard points on the world map, along with the regions where an item can be found.

The combination seems to work fairly well.
Cannot blame the horrendous drop rates on "Spinal Dust" and "Rotting Hearts", in the BE newbie zone, on the quest tracking options.
That's the first horrendous collection so far... gave up before finishing on the first toon, let alone do all five toons.
