I've already got the B&H Impact stand/umbrella kit, so I don't know if that makes a difference with studio lights, but I'm looking into getting 1 of these 2 kits. I'm not sure which direction I should be headed towards as far as going the AlienBees route or the Calumet route.
I've also got RF-602 radio triggers, so I don't know the compatibility with these studio lights.
I've been considering getting:
Alienbees 2x B800 Flash units ($280 x 2)
Alienbees Vagabond II (when they are available again) ($300)
or
Calumet Genesis 400 2 light kit (includes stands umbrellas) ($470)
Vagabond comparable power unit (I need suggestions on this one) ($???)
I know the common pros/cons between the two like:
1. AB color shift issue
2. Genesis slow recycle time
3. Genesis can use elinchroom modifiers?
Obviously the price is a lot cheaper with the Calumets, but I don't plan on going any further than these lights as it's just a hobby for me.
Future prices of modifiers is also a concern for me.
