Hi Ian.
I've just had a refurbished one from this guy:
https://www.ebay.co.uk/usr/shrops_sales
Excellent service, not quite as described - actually in better condition
.
I had an eBay "chat" with him and it was very obvious that he knows his stuff and explained what he'd done and why. Came with Win 10 Pro.
Maybe worth a look.
Good Luck.
