Quest 3S Vr gun stock that doesn’t cost all 4 limbs plus an eyeball?

Trying to find good gun stock that doesn't cost 110 dollars stock not included. Something around 50 to 100 that's actually good quality. Looked into protube Vr and the wield Vr OneStock but it's way too expensive. Any recommendations or should I just take out a loan and buy one of the listed options above? Why are they so expensive anyway?
