We got some too; $222 for 4 wheels, plus $60 in hubs if you choose to use their hubs. The difference in weight between these mecanums and other comparable AM traction wheels on a 6WD is only 2lbs total (6WD = 6 wheels * 0.5lbs, Mec. = 4 wheels * 1.25lbs).

The real cost/weight savings for 6WD comes with the transmissions, not the wheels; yet there are other factors that 6WD must take into account such as chain, tensioners, and sprockets. Mecanum wheels can pretty much be direct drive and maintain a decent speed/torque balance with the available COTS ratios. Keep that in mind.
