as in Think Tank!
I love Think Tank bags and most of their products, but $500 for this bag is way overpriced. You can get the really big Pelican cases for less than $500, and the outer shell is much more solid on the Pelican cases. Waterproof too.
I like to keep my heavy stands and all lighting gear not in the same bag as camera gear. And I don't even want my Alien Bees in the same bag as stands. I have Manfrotto and Avenger and Mathews stands, adapters, boom poles, drop down pins, etc... they are heavy. I need two bags just for that heavy stuff. And then I put one bag for monolights and modifiers and vagabonds.
I end up with 4 bags if I need to bring a full set:
2 bags of stands
1 bag of monolights/modifiers
1 Pelican case of camera gear
I also have a beauty dish that has it's own box, doesn't fit in any of the bags with other gear. So it is almost like a 5th bag. I can't imagine having to get on airplane with all this gear. The extra luggage cost to fly this gear would be more than a rental fee. I would just rent all lighting if I had to fly to a location, and just bring my camera and lenses in my airplane carry-on Pelican.
FYI: B&H has a large in store section of used bags and cases. You have to go in person to purchase though, and also the inventory changes daily. But they always have a large amount of LARGE size Pelican cases and other hard shell cases on wheels. If you know the model number of the case you want, you can call on the phone and they can look it up to see if they have used ones in inventory - but as I mentioned, they go fast, so sometimes they come in and never make it onto the inventory list. And they are about 50% off new prices. They are worn, but they are fine - work 100%. Great way to save on bags and cases. Many production companies come to B&H and liquidate all their gear all the time. Lots of trade in and used gear.
