I got the, and i really like it.
You will have to use the Beta drivers in order for it to work, that includes for your X52 too.
Not sure if you seen the differences, but there is no 3D view of your stick in the SST, and you can't specify the profile you want for the Quadrant via your X52.
(Though I haven't checked for up dates since it first came out)
SO make sure you do it b4 you get in game.
I also have the CH Quadrant to compare it to.
I do like the Siatek better. But probibly bias since I have the X52 and peddals with it.
