New or 2ndhand.
There was a shop on Chunghsiao E. Road between Hsinsheng and Chungshan, on the south side of the road, that sold all sorts of things like this. I don’t have any more exact information, however. Sorry. If you can spare the time to take a walk down that stretch of road it might well still be there.
Thanks, I’ll check it out.
Furtigurn,
What kind of projector are you looking for? A basic or a high-tech and high quality one? My husband was eventually considering selling his high-tech projector (will send you the spec if you are interested) because our apartment in Taipei is too small to fit this one.
