Ever wanted a vintage computer or computer part but were dismayed at the shipping costs when sourcing these from overseas? It's possible that someone in New Zealand has these items for sale, or they may just want to dispose of them but prefer that they went to a good home.
If you're looking for that certain thing, post a notice in this forum. You never know who might be browsing.
If you finally get what you're looking for, just post a follow-up note to let people know you no longer require the item.
