Check out Gilles Berthoud if you end up buying new mudguards, SJS have the narrower version (40mm I think they are). Nothing like as expensive as Honjo Kokens.
For fancy shiny racks have a look at Nitto, Planet X stock some of theirs.
If you want second hand then as you were, keep bumping your thread and ask on RetroBike too.
If you go for Nitto make sure you check the rack's height for wheel and guard clearance as they come in various sizes, and it isn't always clear to the retailer which one they are selling (i.e. at Planet X).
