I agree with what you are saying, I guess it is up to the individual. My thought basically boils down to I would rather get a percent or two less profit from a domain but not have to go through the researching, registering and worrying of using one I had not used before.
That reminds me of an anecdote of when we realized my younger brother knew the difference between "cheap" and "inexpensive".. he had a pen that broke and got ink all over his hands and complained about the "cheap pen".. my mother said, "don't you mean inexpensive"? And he replied, "no it's cheap! It broke!"
