Think about why they're selling it if it's such a good flash. They want to get rid of it because it's so hard to use! They're going to put the money towards the much easier to use and better SB-700. If I thought the SB-600 was that good, i never would have sold mine. I was so glad I sold it and got the SB-700.

I currently have an SB-600, but I will eventually invest in a SB-700, because I need another unit for the sake of additional off-camera lighting. The 700 is a more up-to-date device and the user friendliness of the 700, out does the 600, but the 600 does have a slightly more powerful illumination. Compare the specs of both units.

I'll take the ease of use over "slightly more powerful illumination" any day. Also, the SB-700 is good for both FX and DX cameras. The 600 is a good flash...don't get me wrong...but it's just not user friendly at all. It will certainly come in handy when you're using it for a 2 flash setup, no doubt about it.

I ave used the SB600 a couple of times and also the SB800. I too was looking for a flash unit and settled for the 800. I am very happy with he unit, although I don't use it very often. I have not used the 700, but I would imagine that it is a nice unit.

the guy said he was selling it because he does not have time for photography anymore. He bought his equipment about 6 months ago. He is just trying to make some of his money back. I got him down to 150.00, which in my opinion is more than reasonable. I am skeptical about buying it. I feel more comfortable buying a product with a warranty. I am not to fond of stuff that is not user friendly. As well, the fact that the 700 is more up to date is a major factor. I just hate knowing that I can save more than half the money if I go with the 600. I am still deciding what to do. Thank you everyone for the feedback. It really comes down to a not so user friendly flash with a low price that is discontinued and no warranty versus a higher end flash that is more expensive that will come with a warranty and is user friendly. Tough choice.

just bought the sb700 today. I am very excited! Can't wait to learn everything about it and take great photos with it. Thank you everyone for the advice. I really felt like I made the right choice.
