Brunner is expensive, has limited mounting options, does not work with DirectInput without jumping through hoops using 3rd party software people struggle with to this day, even when it's working has connectivity caveats, the power cuts out if you hold full force for 20s or more, it runs hot. I've followed the Brunner threads on ED since it started a few years and it seems endless. A brunner owner @Sunshine recently found his way here to make a vpforce and can elaborate if he wants.
Meanwhile VPForce is plug and play with DirectInput, can output full force indefinitely since it has outrunner motors and active cooling, has a GUI to further augment profiles for planes/sims or make spring or damping profiles for sims that have nothing, a telemetry extraction app to enhance or replace shoddy feedback on sims that are lacking, costs way less, is available in kit form so crafty folk can make their own easily, has 2 unassigned axes that can be used for gain control, fans, game stuff
