If it ain't broke don't fix it... Can you physically see the optic? There is enough dust to impede the unit from operating properly? If it skips under "Normal" use, no bumps, bangs tossed beer bottles (I went to college too
) I think)... It's probably within the 5% to 6% tolerance level... When it does hiccup try http://allsop.com/ and buy from here. Allsop has been around for umpteen years and know what they are doing.
