Hey Jim,
You're probably sick of my by now
.
If you want simple operation, get the Vivitar DF 283 Series 1. The problem of "simple operation" is, well, simple operation. It's p-TTL only. That means it will fire at full power if (1) the camera does not support p-TTL, or (2) the lens is not an "A" lens or newer.
But I'd get one among
these, probably the middle one. But maybe because I've been using auto flash for a long long time.
Just found
this. If you don't want to spend more than $50, it's the one to get. It has GN of 120 (AF280T: 98), 3 aperture settings (AF280T: 2) and 5 manual ratio settings (AF280T: 2). It doesn't have as many features as the SB24 but it's only 1/3 of the price.
I don't make your life easier, do I?
