I fly only WW2 era simulators, IL2 Sturmovik, Battle of Britain and European Air War, and the combo I have found most satisfactory -after trying many, even the famous CH products- is this:
-
Saitek Aviator Josytick: http://www.saitek.com/uk/prod/av8r.htm
Well built, hard enough spring, throttle comfortable to use and many programable buttons. The central red switch is three position, so it multiplies by three the original 8 buttons on the back pannel, plus the weapons buttons in the stick.
-
CH pedals: http://www.chproducts.com/retail/pedals.html
They liberate your joystick from that function and you really notice the difference of not having to twist the handle to yaw with the rudder. Plus, since throttle and stick feel already realistic, you get the full inmersion as only rudders were in an unnatural position before you start using them with your feet, as in real aircraft.
Alternatively, the Saitek pedals are also available for similar price, and seem to be good.
I consider this set up superior to a simple Joystick/throttle combo, as IMHO having the throttle separated for the left hand is not as inmersive and critical for good control as having pedals. My combo also isn't very expensive.
I'm also considering purchasing now a CH Yoke:
