Personally I could not agree more about the phantom. Not many markers stand the test of time and maintain their popularity, and for good reason, as the phantom.
Another worth noting for me at least is the basic model 98. I can't think of a marker that has been more readily available to get people into the sport with its visual appeal, tough design and simple mechanics. A marker that can compete all day on a recball field, be easy to maintain and get parts for and as customizable as you can think of! Pretty much a classic for any list really.
