30 seconds wiping or 30 minutes sport-dotting. I'll take clean optics for $400 Alex.
I used to work in film and video (visual effects) as an engineer. Part of my job was to QC and recognize things like that unfortunately. I can't tell you how long it's taken to get my brain to relax when I'm just watching satelite TV because of the pixellation. I used to hate going to the movies because of all the film trash and burns from trasfer. My eyes are always drawn to what's not right as opposed to just enjoying what IS right. :-)
