I tried one a while back, and the setup was a PITA so I sold it and bought a Redding BR30 and polished the hopper. I would still like to try one again someday, but the largest extruded powder I have been using is 8208xbr and that meters pretty well in my BR 30.
You could purchase the setting guage to make setting up the charge tubes quicker, but that is an extra $60 on top of the $160 for just the basic set up.
I think if you were using mostly large extruded powders all the time than a Quick measure may be a good purchase.
