I took Robert's advice and went with TPA last July when I was up for renewal.  That saved me about $600 over St.Paul who had covered my previously.  Unfortunately, TPA was not able to cover me through Scottsdale this time for the reason quoted above (no longer offering E&O).  Just got my new quote today - $2096 from Lloyds of London, single abstractor, under $100k, $1 million coverage.  It still hurts, but sounds much better than the $4k Thomas has been quoted.  Call them up!
