seems like it doesnt matter one bit what kind of projector you use, and that projector has been popular lately and should suffice. On the software end, spaghetti should suit your needs. Its very easy to display single frame images with it, and if you have a remote for your DSLR that would probably make life easy.
Im trying to save up for Pangolin Quickshow, I have a soundcard DAC + audiolase correction amp, and a spaghetti license I wouldnt mind getting rid of to get me that much closer to QS. PM me if interested.
