I have had similar experiences. It can get quite frustrating to get what we
would think would be a very common 'widget' or 'gizmo' for sw use and to
only be met that blank stare after the inquiry. A suggestion, I have a
Radio Shack outlet store in my local area that carries most of their
discontinue stuff. I have lucked out in the past going there as opposed to
the mall/store front type of Radio Shack. May want to see if there is an RS
Outlet Store in your local area.
Hope this helps and keep the faith!
