I doubt that they would suppress 1200 within the approach control area
around a class B airspace (ModeC Veil)

Before you invest in a transponder, call the facility with radar coverage
in
your area and find out if they routinely "supress" VFR codes during the
times you fly. When the screen gets busy some facilities supress VFR
codes,
and so a transponder would in fact be a waste of money.
