$20-25 would be a decent price for the 32 GB drive here.  Compare that 
to the 5 image DVD's I would need for the same installation.  A Verbatim 
50-pack of DVD's I can get here for about $0.30/DVD, so cost of the DVD 
set would be about $1.50.

That's a big difference, especially for something to give away with an 
older computer.  It's a backup measure that many people will never need, 
and it doesn't justify too many $$.
