I have a 3000. I used to have a 2000. I have never been very happy with the brightness of the 3000 as opposed to the 2000. I am considering getting either a 3500 or a 7500, however, I do not have anyone local that sells the Pronto so I cannot experiment with one first. Can anyone with experience on these units comment of the relative difference with regard to the contrast/brightness of the screen? Of course, I assume that the 7500 will be the best since it is color, but, overall, how bright is it? How much easier is it to view with background lights on etc?
