Thanks to all who replied to my query:

I can summarize the replies as follows:
One reply from Switzerland said the LX was cheaper there. The
second said that the IPX was no longer sold there. Replies from
the US and Sweden both reported the LX cheaper.
firstname.lastname@example.org gave a useful summary of the LX's new
"Here are the reasons why the LX is more expensive than the IPX:
- LX has onboard ISDN support, IPX doesn't.
- LX has narrow/fast SCSI (max 10MB/sec), IPX has max 5MB/sec SCSI
- LX has 16bit (CD quality) sound, IPX has 8bit (phone quality) sound
- LX has GX+ framebuffer (supports double buffering), IPX has GX
[In Australia at least the standard LX comes with a GX, the GX+ is
a A$500 extra]
- LX has onboard 10baseT tranceiver (but needs conversion cable
for AUI), IPX has only AUI (no conversion cable needed).
- LX has parallel port, IPX doesn't.
Caveats: - The LX only runs Solaris 2.1 aka SunOS 5.1. The IPX supports
older versions of SunOS (4.1.1 and later) as well. Make sure
your software runs on 5.1 if you choose the LX
- SunOS 5.1 doesn't support the LX parallel port, so don't
expect to use it right away.
Recommendation: unless you really need an LX feature, get the IPX. Save
your money to upgrade in the future if necessary."
and email@example.com adds
... the LX has a smaller cache but a wider memory bus...
