Have MSFFB2 and X45 for 6years now, probably for the next 6 years, too....
(have 3-4 MSFFB2 in stock)
X45 throttle is good, X52 throttle is better (more sliders

).
I would love to have a Warthog throttle but price makes it less sensible.
I solved my problems by buying two Saitek Throttle Quadrants extra so I have enough "sliders" for trims, radiators, prop-pitch for a twin engine fighter such as ME110.
The nice thing is that you can setup double throttles in CoD so that I have the throttle of engine #1 (or all selected engines) on the X45 but at the same time I have a throttle for engine #1 and a throttle for engine #2 on the throttle quadrant as well.
Summarizing, X45 Throttle is great value for money.
In addition, you can use the additional keys on the X45 Joystick to set up other keys as well (I have the Eject procedure on the SAFE button on the X45 stick).
