Just ordered one of these from my friends at Banggood.  I've placed 3
previous orders from them and they all arrived safely after 3 or 4
weeks.  Nothing over $10 though.  I have my doubts how well it would
go if there was a problem with a purchase.  Anyway, I've been wanting
one of those inspection cameras and thinking of ways I could make my
own cheaper/better version.  I recently got a windows netbook, so
this will hopefully combine with it to provide a handy tool for
exploring the heater box or other hidden corners of the
vanagon.  This is advertised as being 10mm in diameter so should also
fit through spark plug holes.  I'll report when I get it.
