[QUOTE="blockend,. How about process paid GAF (Agfa I think) 36 exp slide film for $3.29. Hard to imagine today.[/QUOTE]
I can't be bothered to work it out but allowing for inflation from when the advert was printed, I think in real terms today, we may even find modern prices are quite reasonable.

£18.97 or $25.36 in today's money, accounting for inflation. In 1994/95 I was using a lot of Fuji Sensia process paid slide film, which cost £50 for a brick of ten, or £5 a roll. £9.14 or $12.22 in 2017.
I had my last Sensia processed by Fuji a couple of years ago, before they pulled out of envelope slide processing. The nearest available film is Fuji Velvia at £13.95 + £7.89 for processing and mounting. £21.84 or $29.20 per roll.
I went further back. I have an old film box from 1978. The film was Agfa and cost me £2.20 for 36 exp process paid. The inflation over the intervening years according the a table issued by the Office of National Statistics, would make the cost for the same film today around £22 so using the present day Agfa and commercial processing it means the price equivalent is about 50% of the value in 1976. So as I thought....it is proportionately cheaper today, exactly as blockend has found.
As for CDS not responding quickly enough......they were used on the Nikon F Photomic and they worked with a motor drive and that came out before the XK/XM. But to be honest I prefer the Minolta over the Nikon F/F2. The F2 used the later cell (I forget the name) was it a silicon photodiode?
Of course the F's CDS cels were just as slow as any other CDS meter implementation. But unlike the XK, it doesn't have aperture priority and it is assumed in motorized mode that the series of shots will all have been metered the same regardless of changes in light. I suppose that with a motorized XK, design goal was that it would have to be able to aperture priority for each frame. But of course with the CDS cels in the original AE finder it would not be responsive enough. I suppose at that point it is a management decision.
Minolta released the AES finder with SPD cels and Nikon also introduced SPD cels in later finders for the F2.
