Looking at other posts, the most suggested place to get refurbished drives is ServerPartDeals but the shipping + tax to Europe is brutal.
I found this one but he has only 35 drives sold: https://www.ebay.it/itm/404523811058?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=LLFi6ZEISiG&sssrc=4429486&ssuid=DzL4hzgbRtu&var=&widget_ver=artemis&media=COPY
Does anyone have specific eBay seller or place to recommend that is Europe based?
