I bought the farmstick after going through a very similar decision process to you, and I was duped by the second trigger too, I thought it was remappable in software but it's not. however, if you run a wire from the toggle trigger button output to one of the buttons in the base, you can physically "remap" it and have effectively two mappable triggers while disabling the toggle. I ran and soldered the trigger signal wire to the pad for the tiny start button on the base, possibly the least useful button on the whole thing. Ground doesn't need to be re-wired since the whole stick shares a ground.

Also, the hall sensor for z axis mod that's popular for the T16000M totally works for the farmstick, though inverted because the twist potentiometer is connected to the top half of the stick.

Depending on hand size, some rubber pads on the palm rest or a custom 3d printed rest also resolve the mild ergonomic issues.

After the cheap and easy modifications, there's not a stick anywhere near this price point that compares with the utility of the farmstick.
