I've owned a bunch of meters in my life. I have probably 8 of them right now even. The SBC is one of the best meters ever made.
The Sekonic L-898 is the best lowlight meter. It is not cheap at $600, but it is the best. Incident metering down to EV -5 and one degree spotmetering down to EV -1.
The Luna Pro SBC only meters down to EV -4 for incident and doesn't have spotmetering unless you buy the bulky and rare Multibeam attachment, which does not work in very low light.
