TIS and What could have been

Unnerveing thing happen to me today.
I have TIS displayed on the Garmin 430.
I was 15 or 20 miles north of Moraine (I73) in southern Ohio and
talking to Dayton Controller under Flight Following.
I'm at 4500 ft and landing at Moraine. I request (I'm in his air
space) the controller that I would like to start my decent and he says
cleared to decend. Shortly, the display squacks and says "traffic" and
I see a traffic indicated at 500 ft below. I tell controller that I
have traffic on my display 500 ft below and he says "Yes, it is a 172
going into Moraine also."

So now we have a low wing (my Archer) above a high wing (172) and I
have been cleared to decend. I tell the controller that I am stopping
my decent and turning left 30 deg (and speeding up). He did not
respond. The 430 display over the next minute shows seperation and I
turn back to course and see the 172. I continue to keep my speed
greater that his and we both land without further problem.

I think TIS may have saved my ( and others) life today and the FAA is
decomissioning the sites with the explination that ADS-B is going to be
better when they get it implemented in the next few years and an an
inexpensive plane electronic becomes available.

God, I wish I knew how to stop this decomissioning of TIS before ADS-B
is widely available. My life (and maybe yours) may depend on it.
