The Minolta and digital Pentax read identically. I've had both, and find the Pentax a lot faster and more intuitive to read, and more rugged too. My oldest one is now nearly 50 yrs old, has gone through hell, and is held together with black electrical tape, but still reads correctly! (It was recalibrated twice over those years). I have several. My latest was purchased "like new" a few years ago for only $200. Lucky find.
