I have a T-flight after having a couple of Logitechs. The throttle certainly gives some extra functionality for the left hand. I've also tried some X52's just to find out how they feel, as well as CH gear. After a Logi the T-flight will feel more familiar than the more expensive ones, the grip is almost similar although some buttons are either missing or in different places. The X52 instead has more than enough buttons and knobs.
For a one hand twisty I'd recommend the Thrustmaster T-16000m. It's among the most accurate sticks on the market due to its ultra high resolution and HAL sensors. And it has the Logitech measurements, too. IMO it's a little sturdier than the T-flight. I'm currently using the T-flight for throttle and the T-16000m for stick, combined still below your budget!
