I have the great Sb 800 that I use on my D7000, D600, and D 750 and I power them with Calumet Powerblock 900, which is a great unit. It's light, powerful, charges quickly, recycles quickly, and is a great buy. I also have a Quantum Turbo that I use with A Sb 28 on my F4s that still works well, but is very heavy, and very expensive.

Add me to the list of people who "fell for" the SB-900 "upgrade" Thankfully, I kept my SB-800. Not sure if you knew this, but for those using Yongnuo YN 622 triggers, the SB-800 doesn't play nice with iTTL. They work fine in manual. My SB-600 and SB-900 work fine in iTTL. I've googled the issue, and it seems that everyone knows of the issue, they just haven't exactly found a fix for it. Soooo, I guess I'll keep the SB-900 for off camera work, and SB-800 for power and not having overheating issues. I'm beginning to think I should move to 3rd party flashes. They probably still have issues too, but 1/2 the money for the same issues.
