You can get cheeper ones without the glass...  I like the place where
robert gets his.  They are worth $40.

1.  They look like a school ID that has been laminated.
2.  They are just the right size of the mirror that they will stick to the
LCD.  This is neat because you don't have to mount it.  It will stick there
for a long time.

Whats the site address for All Electronics?
