Any stick will give you the same basic functions. With the game settings, you can disable rudder function on a twisty stick, or play with deadband and dampening. Your dislike of twisty rudders need not affect your next stick purchase.
I've personally used (between AW, AH, and AH1) 4 logitechs, 4 saiteks, and a CH gameport stick. The CH stick had the best feel by far, but gameport connection and 4 way hats meant that was a no go for me. I picked up a Saitek X52 from one of the big box stores, and have been happy with it so far. Much better feel, and far more features than the cheaper Logitech and Saitek models, but not nearly as expensive as a CH HOTAS setup. Also, it will allow you to disable the twist function via a latch.
As an added bonus, like CH gear, it comes with software allowing you map all sorts of interesting features that the game interface does not.
While my first Saitek (an old Cyborg) lasted from AW through AH2, the next 2 didn't last 6 months, and at this point, I've probably wasted enough on budget sticks to have purchased a far better setup.
Having said that, had I the funds, I'd get a full USB CH rig without hesitation. The old CH stick I have is 11 years old, and (besides the outdated plug and 4way hats) absolutely perfect, despite many years of abuse through the cartoon careers of 3 different simgeeks.
