Thanks - was coming to that conclusion myself.
It seems a 6 speed with the smaller (44T?) chainwheel would give an almost identical range to my Fuji on the middle ring, which I find perfect for daily use. Looks like I'm after a later M/S 6 L/R or a "C-Line Explore", which seem to start where you suggest or a bit more.. the current version of the latter retailing for about £1.5k new.
I paid £950 for my C Line Explore with Brooks Cambium, not the cheapest out there probably but it’s not black (many for sale cheaper were) and the very lovely previous owner had it serviced by a Brompton dealer at a cost of about £110 for labour and parts, important peace of mind for me. I had been watching a 10 year M6 on eBay before that which ended up going for around £850!
