So how does this compare to a store bought handbrake such as the Fanatec handbrake or Aiologs handbrake? I'm assuming that it won't be as solid as the Aiologs one but is it close to the Fanatec?

Fanatec and Aiologs handbrake use potentiometer like my DIY handbrake, so I thinks it's same quality. the both are solid because they are in steel.

I find my handbrake have much better design than the handbrake you listed.

There should be not POTs but Pressure Transducer for 500 or 1000psi.
