Hi,
I have the YN-465 and am VERY happy with it. (Cost me £40 ~ $60)
I do very little photography with a flash and wanted something simple that just worked with no real effort from me.
This flash is full ETTL or you can dial in manual settings from 1/64 up to full. I must admit I've only used it on auto and been exceptionally happy.
I used

Here is a photo I snapped from a New Years Eve party. Indoor with average lighting taken at 70mm, 1/40 sec, ISO 400 with the flash bounced off the ceiling. I did take some non flash shots too but deleted them as they were all unusable! Sorry, no comparison for you.
