First, I don't necessarily say this to persuade the OP to use a light meter, it's a tool, use it or not, IMO. But if not, and one is continuously not pleased with their pictures, perhaps they should revisit the idea.
But spot meters, over rated? Not if you want to measure a spot, right?........especially at some distance from the camera. There is quite a lot of incompetent useage of spot meters, IMHO.
