ok the questions are starting to stack up so i need to write them down.
i under stand there are different zoom levels that are easier on the bulb?
how often do you have to clean the screen? (understanding this is relative to the environment but an approx will certainly suffice).
can you leave the pull down model "pulled down " or must you return it when not in use?
what is the desired angle of pj to screen?
how critical is ambient temp? id like to be able to take the pj outside for "drive in viewing " on my deck.
i know this is a short list but i get clutter head so easy these days i had to do something with it. thanks for the info guys, dan
