TX

TX makes stabilizers for the enthusiast end of the market and nothing else. Three sets here, priced $12 to $18.

Stabilizers are the component most likely to ruin an otherwise good board — a rattling spacebar undoes a careful switch and keycap choice — and the enthusiast brands compete on tolerances rather than features. TX sits alongside Durock, Wuque Studio and C³Equalz in that group. Compare against the screw-in shelf as a whole before deciding: at this end of the market the differences are small, and fit with your specific PCB matters more than the badge.
