True enough. As it turns out, the Stage 2 I ordered was a 75-80072. It's got the torque tube, sealed box, and Mega Cannon filter. The Stage 2 that was quoted at so much less was a 54-10073. Different enclosure, different filter. The prices I saw just about everywhere were the same, or very close anyway. You're right, though. Gotta give people a chance to respond.
