hi, i was wondering if anyone here has viewsonic projectors? is viewsonic a good brand? any issues? i foud the viewsonic PJ513DB for under $500 bucks and even though the resolution is only 800 x 600 that will be enough for me. i currently have a toshiba with the same res as above and has served me well so far. but i need a new one... also... i read that the model above comes with a 3 years warranty. any input from you will be appreciated. thank you all :)
