I'm thinking about dipping my toe into some portraiture, and I'm looking at studio strobes. I was thinking about picking up a few AlienBees B800 units. It looks like they are $280 from the website. Then I was looking on B&H and they carry the GODOX strobes. I've read some pretty positive things about their equipment. Can anyone offer a comparison between the two? Also, I can't seem to figure out the difference between the following lights: SK400ii DP400ii GS400ii QS400ii They all seem to have the same specs. Thanks!
