I use a Master III for general use, with and without the Invercone, and an old Lunasix for low light. I don't have much trouble reading the Weston, when it's too dim to read the numbers I reach for the Gossen.
I have a spare Weston, NIB, a spare LunaPro, NIB, and a spare Lunasix. I'm set for life. Several lives, actually.
