The part Don sells is more expensive than other available from other supply houses by about $20. However, there's no comparison on the quality. The turn signal cancel cam on the less expensive model has a flimsy feel to it, and gives me impression I would be buying the repair kit in a year or so.
One thing to watch out for on this reproduction part: the color of the green wires. The factory original has a dark green wire, and a slightly lighter shade of green wire with a white tracer. On the repo part, the light green has a white tracer that is nearly impossible to see, especially when you are upside down under the dash trying to find out why you turn signals work but your brake lights don't. Make sure you get the two lined up correctly or you'll be stumped for a while figuring it out.
Verdict: Worth the extra $ for a higher quality part. Changing this part is a pain, and you don't want to do it twice, even with Don's helpful video.
