The original question, as Craig already stated, was ambiguous as to frequency
In any case, if I were running an automotive shop where time is money I'll
have a full case of the correct (and expensive) tools. But if I'm doing one
or two rebuilds per decade at most, not only would it be a waste of money to
buy the puller, I'm not going to likely be able to find it eight years later
when I need it again.
Now, lest you think I'm all duct tape and bailing wire, there are a few such
tools I have had that I used in my previous employment, like a Delta OIB-1,
and a Rohde and Shwarz spec-an. Don't need the OIB-1 anymore; it's gone to
Sumter SC now, where it will be used. So's the spec-an. Those two tools
together cost nearly $10k new, but I did enough 47CFR73.44 work to make them
worthwhile for the short time I owned them. And I got a tidy sum back out of
them when I sent them to their new home.
Similarly, when it came time to spec out RAID arrays for storing one-of-a-kind
historical astronomical photographic plates, the choice was clear. EMC ain't
cheap, but it is good.
But, for one-off copies of not so critical stuff, sure, I'd do up to maybe
100GB to DVD's. Beyond that, with 160GB USB drives like the Seagate
FreeAgentGo running less than $100, the choice there is clear at least to me.
For more critical stuff... well, actually, I've been there and done that for a
radio station's entire audio library, but it was to CD and it took almost 400
of them to hold the roughly 250GB of audio (650MB archival quality CD's,
stored in a media safe). This was done over a long period of time (my
recollection is nine months or so), and was done by the board ops during 30
minute broadcasts during their airshifts. And this was on Windows, so it's
OT for this list.
It was also long enough ago that they've gone to hard drive copy since then;
but the CD archive did get used once when one of the several 27GB Maxtors bit
the dust and the music that had been on that drive had to be restored. Since
we used high quality media, the restore went off without a hitch. This was a
year or two after the backup had been written; those discs are long gone now,
so don't know if they are still readable or not. I do have some Plextor
media we got with the first 12x Plextor we bought that are still readable
