I am looking for a great Desk Top Base Station Mic. I know that many of the very best can no longer be found in retail outlets and must be found in classifieds, online auction sites, etc. I also realize that there are many still being made, new off the shelf, so to speak. I have done a lot of research and read a lot of reviews and I believe I ended up mishcombobling myself with that subject.

Which would be your choices for the top three, either no longer made but can still be found, or off the shelf.
