It's a simple enough camera. It forces you to slow down (manual focus, manual shutter adjustment, manual aperture, don't forget to advance the film, etc.). Oh yeah, and do all the above while tracking a moving object on the reversed image finder - well that's where it gets a little tricky.
If you carry an iPhone in your pocket, there's a good metering app out there called Light Meter. It seems plenty good and would save you from carrying a separate meter. Maybe not for the purists, though. But I like cheap solutions.
