I once (late 1997) did a survey for a public radio classical music group.
it took weeks...

Naxos had the broadest repertoire of AVAILABLE music on CD's that you could
order in the US.  EMI has them in one form or another, but try to get some
of the CD's you need...  And name something you cannot get from Naxos...
I was once delayed 6 weeks on a Naxos order, never longer.
