For our '05 bot, we ran a pair of FP/AndyMark Planetary pairs into a FRC/AM (same reduction i believe) kitbot type single speed gearbox, then ran the output of that single speed gearbox into another single speed gearbox. The reduction is extreme, but if you remember how big the lever arm was on our '05 tetra bot.... it needed a TON of torque and a teeny weeny bit of angular velocity. (So much torque that it once exploded its #35 double wide chain sprocket... into five pieces.... one embedded itself in the wall of our mentor's room....

)
So... yeah i see where you can say that there is a market for an 'in-between' level of gear reduction.
