Dude, just go find a guy that cuts glass and bring him a bigger mirror
than you
need. We busted a Sony mirror at the shop once. Geez, we don't even care
about
the money, what happened is that three mirrors arrive in a row all broken.

we already HAD a broken one !

Many RPTVs no longer use front surface mirrors, the performance difference
is
just not worth it. If it uses two mirrors the situation is different, but
I'm
pretty sure that one only uses one mirror. You'll never notice the
difference.

The customer may never notice the difference and a tech who isn't interested
will not notice the difference. It is a subtle enough effect that unless
you have both mirrors there to swap and compare, the picture with the normal
mirror may look acceptable. However, for the critical viewer, the
performance difference between surface coated and standard mirrors is
certainly worth it.

I have made direct comparisons several times and there is a very clear
difference in the picture. It is the cost that is the matter for the
manufacturers and performance is a much lower priority. In a head to head
comparison most consumers will choose the brightest picture with moderate
detail rather than the more high resolution picture. Since the mirror
difference affects detail much more than brightness, it is more sales
effective to cut costs and crank up the torches.
