pulled the trigger on the FrontRunner, shipping will be much cheaper as it's a kit. But I really liked the dovetail design on the ARB. it's so easy to add and remove your gear. I went with that and haven't regretted it. Mine is a full rack and she is noisy (whistles some) when empty, but put a load on it and it's quiet. It's actually the smooth flow that causes the noise. Break it up with gear and it goes away.
If you are in Utah, I ordered mine from Cruiser Outfitters and picked it up, that saved me on shipping....well $60 in gas I guess.
A front runner will arrive to your door. Then you put it together.
