When I started getting into the hobby Heidi Ott was pretty much it as far as more affordable articulated 1/12 scale dolls went. They came in 4 basic designs: young and older woman, and young and older man (the Caucasian types came with blue or brown painted eyes, and there was a Black version of the younger models). Sometimes the male dolls have flocked hair and / or facial hair, while the women come bald or with tiny little wigs.
As the dolls become harder to find the prices only increase - you'll be lucky to find a basic undressed figure for less than £30, and the dressed ones will set you back at least £50+. In an age when you can get a Figma type doll for £4, as cute and well designed as these are, you'll probably only want to pick them up if you happen across them going cheaply.
Heidi Ott also made smaller dolls in 1/12 scale meant to be teenagers, kids and babies - they have cloth bodies and plastic limbs:
There were lots of dressed dolls released, primarily Victorian era but also a fair range of more modern looks. Check out the catalogue pages for dressed babies (one, two), toddlers, children, teenagers, and adults:
In addition to the shoes and sundries shown above - and cute little necklaces - you could also buy clothing separately:
