The first thing that you need to consider is if your Overhead Projector will need to be portable or stationary. If your presentations require you to travel from location to location then you should certainly consider having a projector that offers you the portability of a briefcase type Overhead Projector. These projectors easily fold into the size of a large briefcase making them easy to transport, even through an airport. If you will be making your presentations say from a Boardroom or a Classroom where your Overhead Projector will spend most of its life then in most cases a portable Overhead Projector will not be necessary.
Once you have determined which type of Overhead Projector best fits your needs , then it's time to consider these options: Lamp changer, Open or Closed Head, HiLo Switch, Lumen Output (How bright the projector is), Singlet, Doublet or Triplet Head , Standard Focal Length or Wide Angle. Th.
