I also got the X-52 after a looong time with my X-45.
Unfortunately, it met it's end in a BF2 match while in practice round. The Joystick's base (the one connected to the spring that goes up and down) broke and it wouldn't stay centered. So I thought I'd get X-52. It's nice, less hard movement on the joystick but I preferred the X-45's rudder under the throttle, turning the joystick itself for rudder control in X-52 is a bit weird for me.
Btw, it is just me, or every new Saitek HOTAS must be even more like a Christmas tree? :P
X-36F and X-35T were nice in their black colour, X-45 got the blue, gray and orange happiness and X-52 could easily be a desktop lampshade of sorts. Yeah, turned it's lights off because after the first few hours, they were a little disturbing while flying for me. :D
