What are you looking for?
Force Feedback or not?
HOTAS (hands on throttle and stick = separate throttle and stick)?
Something like a MS Sidewinder Precission Pro?
Saitek X52 has gotten alot of good comments, one of the cheapest HOTAS systems, some like it alot and there are some (quite few) who don't like it at all.
I am using a HOTAS Cougar. Quite a bit more expensive but you said money is not an issue.
Then there is CH setup, HOTAS where you buy a Pro Throttle and a stick of your choice, usually Combatstick.
As for non HOTAS systems, The Sidewinder is a good choice if you can find one on ebay. Cyborg EVO I don't know much about but some like it I know.
Let me know what exactly you are looking for.
