Hmm, this type of thing has been discussed extensively on the list.

All of this type of thing needs to be done with cart manipulation. There
are many, many, examples of this that I have posted to the list. Here is
yet another one.

Probably the easiest thing is to preload the inventory type with this
in catalog.cfg:

    AutoModifier  inventory:no_backorder

You would have to add a DB field to inventory for that one.
It is a flag to signal that it is a one-of-a-kind item.

Then parse the cart at the top of checkout, and:

[perl tables=inventory]
    my @messages;
	
    foreach my $item (@$Items) {
	next unless $item->{no_backorder};
	my $onhand = tag_data('inventory', 'quantity', $item->{code});
	if($item->{quantity} > $onhand) {
	    $item->{quantity} = $onhand;
	    my $msg =
		"$item->{code} quantity adjusted to $onhand, one of a kind item";
	    push @messages, $msg;
	}
    }

    $Scratch->{cart_adjustment} = join "<BR>", @messages;
    return;
[/perl]

[if scratch cart_adjustment]
	We adjusted your basket:
	<BLOCKQUOTE>[scratchd cart_adjustment]</BLOCKQUOTE>
[/if]

You will want to do this in a checkout profile as well. You cannot
stop the border cases of two people ordering at exactly the same moment
without a lot of work, but even that could be done if you tried hard.
