Regarding the xD adapters, I did find some later on after
a tip from someone that you don't have to modify them at
all other than popping off a plastic cover over the
socket for clearance.  The first ones I tried were
rubber coated over the socket and while these worked, I
had to cut them down for clearance.  The other ones
I have you just pop the cover and they fit.  I've
been using xD cards exclusively now for over a year
and a half at least.  No matter which way you go, I would
not consider yourself to be in good shape until you own
maybe 6 working cards.  you're going to want your
system working good for many years, and even 6 cards
can be damaged pretty easily.  So if you want any hope
of continuing Database upgrades, or being able to set
limits, definitely stock up on cards.  There are SM
cards on eBay now, for reasonable prices again, but not
large cards.  xD cards went from being plentiful to
being much harder to come by too...in the smaller sizes.
Some IDU-3's I understand can only handle up to 64Mb
cards.  IDU-1's can handle 8-128Mb cards.  Larger
cards are useless for this task.  I find 64Mb to be the
best deal, because some log files can get near 10Mb, and
with 5 recent logs available, you may need 50+ mb just
to download logs.  So I use 64/128Mb cards for downloading
logs and stocked up on 16/32Mb cards for doing routine
things like database upgrades.

Also, regarding the gold contacts, the manual is written
around IDU-3's and I think those use contacts UP, whereas
the IDU-1's use contacts DOWN.  So that is why there
is confusion.

As for the adapters....this adapter is the kind that
I've found to work (although I can't guarantee that
this one is identical).

Auction item: 320420732741

Those use a plastic shell...and you see the lines vertical
on the picture.  The other ones are more square and are
a molded rubber....don't get that kind.
This is an example of a BAD one:

Hopefully that helps.
