For under $50 USD at the time, the Microsoft Sidewinder optical joystick. With no pots and variable resistors, no parts to wear down, no losing tolerances or accumulating centering issues with wear and tear, it functioned exactly the same years later as it did since the first day. The main problem was the pretty light construction overall, particularly the lightweight base, which made it easier to move the whole thing around with any inputs (which is true of most joysticks I've picked up). It didn't have that garish cyborg look at all that's become so popular now. No longer supported in Windows, shame. These things go for hundreds of dollars now.
No one gets out of here alive.
