I bought a pair at a garage sale for $18 about 15 years ago. I assume they
are cheap because I can't figure out the brand. However, they are heavy and
have good optics -- I know because I've got a couple cheap pairs! These are
crisp and clean and bright.

Anyway, they were dirty and (I think) slight misaligned when I got them. Out
care the screwdrivers and jeweller's screwdrivers, lens-cleaning fluid, and
lens tissues. After an hour I had them back together in and aligned (that
took two goes). It's now 15 years on and they are still good -- I don't have
the time to be a really avid birder, but they do get used a bit still. 

How easy is it to attempt to repair a set by oneself? I presume not all are
that easy to open and disassemble and reassemble?

Mine were easy.

I was under the impression that collimation costs about $100, assuming
the binoculars are constructed in a way that allows it to be done at
all. Everyone has different standards, but I'm wondering whether many
Australian birders use binoculars worth less than that.  Perhaps what
the customer was really being told was that their binoculars really
couldn't be fixed.

As for getting it done more cheaply overseas, if the construction
doesn't really allow it, then collimating them might require even more
precise equipment than for more expensive ones and might not be
available.  I don't know anything about binocular construction, so
perhaps my dealer misled me about this.

I'd be very interested to know if your idea is feasible, but I suspect
that it might be more feasible to have the recipients use them with one
eye closed or just send them money to buy cheap ones.  $10 compacts
definitely have their limitations, but are still heaps better than
nothing, some of them anyway.
