Jerry is spot on, not expensive but effective for the money.The term steering 'stabilizer' is actually a misnomer, its correct name and function is that of steering damper. Its job is to protect the steering system by damping out jolts and bumps when driving over dips, bumps, etc. on the road surface. I'd replace it just so the steering system has that protection.
Go with a standard hydraulic steering damper like Rancho sells in their RS5000 kit. Some gas-charged dampers can cause the steering to want to go left due to their trait of constantly trying to expand.
