Thanks guys for the self cancelling turn signal responses. I guess I'm not getting senile - yet.
I went on E-Bay and found that there are a number of different types for sale, including the one that self cancels. Problem is that the 'buy it now' price is $100! No thanks, I can do a lot of manual cancelling with my present unit for $100.
Thanks again for all the responses and again the Stovebolt Page has lived up to expectations. It is REALLY the only game in town!
