Thanks Dave - great to hear that they inspire real passion and the screens can be changed. I prefer split prism for manual focussing, but given the cameras I manage to get in focus, I may not need one!
I'll see how my adventure goes but it does sound like the EOS5 and siblings is the upgrade choice.
Film amateur with a few rangefinders - Leica III, M2/M3, Werra 3 and Zeiss Super Ikonta 534/16 medium format.
Apart from that have a Rolleiflex 3.5F, the odd Minolta XD7, Hasselblad 500cm, a Topcon Super D and an Intrepid 5x4 large format (not the half of it but I am clearing them out, honest).
I do all my own black and white developing at home.
