I'm using a track point with https://uhk.io/ but find it's a little too "fine" compared to the clunky manual nature of the keyboard. It feels like a piece of jewelry placed atop a heavy duty durable piece of hardware.
I love it, but think that a joystick more similar to what is found on an Xbox controller would fit the feel of the keyboard better.
I love my UHK too but the trackpoint is pretty disappointing, even after you mess with the movement settings to make it slightly less janky. The thumb modules are a huge drop in build quality compared to the excellent keyboard.
The next UHK firmware and Agent release will enable you to tweak module speed and acceleration settings, which should make your trackpoint module significantly more useful.
We haven't received bad feedback about the build quality of the modules, so I'm wondering what makes you so dissatisfied.
