Nodal Ninja M1 vs RRS Pano gear, vs?

Want to get serious with my panos and think I need a arco-swiss plate accommodating system to upgrade to from my Panosaurus--which is great for lighter setups, but my D90 w 70-300 was too heavy for it--slippage and vibration issues.

So, I think I'm looking for "rigid and fast", first, and "light and cheap, if possible", second.

Anyone out there using the Nodal Ninja M1? (What does it weigh? How much weight is it rated for?)

...Or the Really Right Stuff pano rigs?

...or want to recommend a system involving Arca-Swiss plates? (I have a RRS L-bracket)

Looking for thoughts to help me figure things out.

Finally, I think I want a Nodal Ninja RD16 "clicking" rotator base for either system, unless someone tells me it's wobbly--thoughts?

Thanks!
