Do you mean in terms of annual sales, or from the perspective of those of us who love the sound of them?
My vote goes for the Cyclone, and the P-10 in that order. The Allertor 125 was always so strange looking to me, something like a Dr. Seuss creation for the people of "Whoville." However, the T-135 is an awesome beast, but I have never seen or been up close to one when it went off. Somehow, I really feel I am missing out on something in life by never having this experience.
