Query: I love this thing.

I bought an Autograph Prism at $250+ to trace art projects for painting. I wasn't very happy with it. It wasn't able to reproduce images as clean as I would haveliked (16x12 or so size). You really had to maneuver the Prism to get the image straight and where you wanted it but bythen it was so close to the wall (for the 12x16 sizes I needed) thatI was in physical pain to try and trace around the machine and the image light.I took the Prism back and exchanged it for the Tracer which was only$80 and I love it. It is much easier to move and position, image is great, does 8x11 sizes really good. I use it inmy bathroom and set it on my music stand at a height thats very comfortable for me to trace the image.I really think it works better then the Prism at 1/3 the price.If your a painter and need canvas size images I'm going to advise you to try the Tracer. I love mine.
