I have one that's in-between. The monitor is always "present", only the keyboard and mouse get (dis)connected. It works fine, since it avoids the biggest problem of adjusting the screen resolution which can reposition desktop icons, etc. The only drawback is a 3-4 delay as USB mouse/keyboard is reconnected. The price was around $50 IIRC.
