I was looking to get an X52 Pro, but most shops didn't have it in stock (at least for immediate same day walk-in / walk-out pickup)
But one of the shops near home had the X55, and the irony is that their price for the X55 was cheaper than most other shop's price for the X52-Pro.
Since it was a birthday gift, my girl brought it for me. I had my heart set on the X52 Pro, but I'm warming up to the X55, and after reading people's reviews and comments about it, it was probably the better choice due to additional/more sensitive hall sensors, extra buttons, dual thrust (good for other games, or maybe Elite if they ever add a feature for it).
Either way, it's still a great joystick and definitely trumps my old Logitech Extreme 3D Pro. So what if it doesn't look like a XMas tree like the X52
