I used an X-55 Rhino quite happily but after a year and a half I had bad ghosting problems with the throttle unit. On the outside, the thing still looked great, but apparently wires were wearing thin inside. Still, it had lasted a good while. Shopped around and in August decided on the Thrustmaster T.16000M FCS. After about a month, Im enjoying it very much.
There are pros and cons. I find the Thrust joystick much more comfortable than the Rhino. But I liked that the Rhino had more buttons on the stick. I think I might like the throttle better on the Thrust, its movement mechanic is good, though the more 'rubbery' feel of the Rhino was nice compared to the hard plastic of the Thrust. The deciding factor for me was cost. The Rhino is going for about $250, while the Thrust is about $110. Even if I run into same ghosting problems as the Rhino, heck I can buy two Thrust setups for the price of one Rhino. For me, both are nice and have pros and cons. So with such a significant price difference, I recommend the Thrustmaster.
