Yes, as lustman put it, it's chemistry. For me, a relative newbie, my better experiences have not been with the lower end, but on the $$$ and up. Sometimes it seems the extra $ goes into a nicer environment for the encounter where the feel is more of a home than a jobsite. I think that this is why my one experience at a MP left little desire to return. Even still $ alone definitely does not guarantee that you'll get what you are looking for. pt
