I have mixed feelings about Saitek.
Awesome designs for their products, but I've had some issues with almost all of the ones I've owned.
I started out with their x45 which I loved. My problem came with the connection into the throttle, as mentioned it can come loose and cause MANY issues. So, I upgraded to a yoke. I love the Pro Flight yoke as it was one of the first (affordable) yokes with a separate throttle quadrant. HOWEVER, the servo's in said quadrant suck. I burned through the original throttle lever server within a year. (signal jumps from idle to full power instantly, no reliability.) Because of that I had to make the prop lever the new throttle, make the mix the prop, but at least I could use the old throttle as the mix. (No longer however, totally shot.) I'm slowly working may way through all my options here. And at $150 for a new housing that may not last a year, im hesitant to buy a replacement.
Though I absolutely love their new products and REALLY want to try them. I mean come on.. They have a radio stack, cessna style throttle/prop/mix, autopilot multi use stack thing, general switch stack, the new fighter pedals, a realistic fighter joystick (pressure sensitive, no moving parts) and even instruments. They have some AWESOME stuff now, but with their quality history (for me anyway) I don't know what I'm going to do next.
However, unless you want to get into the $450+ serious stuff, there really isn't much of an option. CH hasn't updated their general FS products since I first looked at them 3+ years ago. So they're fairly outdated now. There are some 3rd party stuff available, but none of it really appeals to me. Which leaves Saitek. Both good and bad at the same time.
Anyway, on topic. I've never heard anything bad about the X52 but keep in mind, I haven't looked hard

I have, however, heard a lot of good about it and it seems to be one of the most popular joystick controllers out there.
