No doubt.  Don't get me wrong, GW and KryoFlux and Catweazel(sp?) and 
others serve a great purpose.  But, most media is not so important.  I 
have some geneology disks a family member worked on in the 1980s that I 
need to archive.  But, it does not rise to the need to flux image.  I'll 
just pop them into a DOS PC and grab the data.  If there are issues, 
we'll cross that bridge then.

My thanks to all that answered.  I’ll probably pick up a GreaseWeazel at some 
point.  Right now I’m trying to judge my need.  I’ve only found a fraction of 
the 5.25” floppies I should have.  For that matter, I’ve only found about 60% 
of the 3.5” floppies I should have.  I’m mystified as to where three big boxes 
are, and those include the bulk of my 5.25” floppies.

Realistically that’s good enough Jim, though I find the way the 3.5” floppies 
are working to be quite useful.  I can take a look at what’s on them, and in 
many cases, I just pull the files off.  As there is no reason to image them.
