These guys now have the new(!) Kodak Ektachrome in stock for the same £70 with processing.
They also offer a digital scan with optional enhancements too.
The Ektachrome has a nicer colour cast than the Wittner rebranded Agfa stock.

I used 'Agfa Aviphot Chrome 200D' and had a digital scan as you suggested. Much better quality than the VHS transfer of my parents 8mm reels in the 80's which were obviously SD quality... well worse than that.
