Having a Shure V-15 IV or V won't take care of all warped
records.  I have one which I use as a backup for my Grace
F9E, mainly for exceptionally warped records, as I generally
prefer the sound of the Grace.  I recently bought a set
of live performance cuts by Maria Callas, one of the records
of which was so warped as to defeat both the Shure and the
Grace on my Sony 2251.  I had bought the set in Europe and
therefore couldn't easily return it.

I didn't try to de-warp the record.  Instead I had a friend
play it on his Sony PX-600 (with the micro-processor controlled
"biotracer" arm) which sailed through it with several
cartridges we tried (Signet, Koetsu, and Ortofon) and 
had him put it on tape for me.

I have read negative comments about these micro-processor
controlled arms (also offered by Denon, JVC and others) and
I'm not sure that I would rush out to buy one in terms of
the general sound quality on "normal" records.  However, for
these extreme cases they seem unique in their tracking abilities.
