68 barracuda turn signal canceller

I bought one about 7 yrs ago on ebay for $18.75 I think it was. Mine has gone out now, and I gave the new one away a few yrs. back cause I thot I didn`t need it when I rewired the car. (dumbass mistake!) Now they are priced $56-$300 on ebay. That`s completely nuts. Any body have an idea of where to get one w/o being Raped ??
Do you need a whole switch or just the cancelling cam? "Turn signal canceller" in your title got me wondering.
