Well, if digits are too small on Minolta, I don't know of one that has them bigger. Pentax Digital Spot has bright red LEDs in the finder, can't miss those, but I'm not sure if this is one to use at night, not even in the dark. Meter needs to be able to measure that dim setting, before there is a need to see what it measured. Gossen's Lunapro SBC is very sensitive, but that has no light. Its Spot Attachment kills some of that sensitivity and makes meter twice as big. Never used Gossen's Ultra Spot, maybe that is something to look at, but not a cheap option.
Personally I'd go with another Minolta Spot M or F, just one that is all good as designed.
