This bad boy is **Only** $4800.00.

And it's great for curls if your dumbbells aren't big enough!

Why are some of these white lenses half black and half white - does anyone know why they were made that way?

I think the white part was to help keep them cooler. Otherwise the IQ gets degraded due to the parts expanding and throwing tolerances out. The grey part I assume is darker so that dirt and grime doesn't show, but this is me speculating.

There's been one available from KEH for $2900 for months now -- even survived those 15% off days. I was seriously considering it, but it is just too damn heavy. I have the A*300, and it is plenty big and heavy, but I can still put it in a backpack and lug it around. This thing couldn't ever be more than 10 feet from the car though...
