I'm looking for a yongnuo speedlite for my nikon d3100. I can't afford a sb so yongnuo is my other option. If anyone owns one id like to hear your opinion and review please. Which one is the best.
i prefer a ttl not a manual one

The YN565 is the TTL version I have heard of - sorry, I use manual YN560's!
