I bought the Polaris unit because it was the cheapest. I paid about $150 for it new. It works well, works as regular and flash meter, incident, or diffused metering. It has regular flash mode, or will tell you the number of "pops" to use.(posted 8580 days ago)If your just looking for the basics, it's hard to beat. If you want a "does everything" meter, then you can look at the others. Brace yourself for the price tag, though.
