I gave up on getting a diopter as all the good ones are no longer made and the
remaining ones have probably been bought up by Moose and Mike :-). Hence my
approach is a lens with good magnification natively. And if you do find one of
the coveted diopters, expect a high price tag. Hence it is likely a matched
1.4X to the lens is the better option.
DZ 40-150 0.16x MFD 0.9m 58mm thread
DZ 50-200 0.21x MFD 1.2m 67mm thread (Pentax T132)
PL 100-400 0.25x MFD 1.3m 72mm thread

For example, in 72mm the Minolta close up lens is priced around $400

T132, good luck finding one of these.
I bought the Sigma AML72-01 (72mm) and is too much diopter (+1.74) for my case.
There was a some diopter discussion on the list around 10/13-14 2020 titled
"[OM] IMG: Macro Experiment with Leica-R 60 Elmarit Macro L"
Check out Moose's excellent notes on 10/14/2020
