I'd be interested in your speedlite setup, although 3k is above my budget.
OK. Here's the kit. Everything fits inside a
Pelican 1514 rolling case, which meets USA carry on standards.
Speedlights: a mix of Canon flash units. I prefer the 430 EX II for size, weight, cost, and
compatibility with the Pocket Wizard TTL system. I have 6 units, though only 4 are in the case.
Triggers: a mixed set of Pocket Wizards, 5 of the
new TTL units, and 4 of the older standard units. The TTL units are mostly used with the flashes on Manual mode. I am waiting (sort of patiently) for the
remote control unit that will let me change flash power from the camera position. Yes, the PW's are seriously expensive.
Stands: Two of the
Bogen reverse fold light stands fit inside. They are tall enough for general use. I also carry two
Justin Clamps -- since this is almost all location work, I use the clamps a lot. I like the
Lastolite Triflash adapters to attach the flash units, but the
Bogen stand adapters are fine too.
Modifiers: two of the 43 inch double fold umbrellas, one shoot thru and one silver/black. A complete set of the Honl modifiers -- 3 snoots, 2 grids, 4 barn doors. They are terrific. Various color color gel filters cut to size -- mostly warming but some color effects filters. Also, I carry a
48-inch Lastolite shoot thru Tri-Grip panel, which is awesome for quick setups -- have an assistant hold a TTL flash and aim it in the general direction of the subject. Easy, fast, and great light. (This panel does not fit inside the case.)
So, as I said, not a cheap system. But, it can be done at lower cost.
Lights: You don't need Canon (or Nikon) speedlights if you aren't using the TTL features. Any manual flash like a Vivitar 285 or the
Lumopro 120 will work fine. The Lumopro has a built in optical slave -- which is an easy way to fire it in the studio, and for $130 it's pretty cheap to boot. A kit of 3 Lumopros is less than the cost of a top of the line TTL speedlight.
Triggers: use the optical slaves. Cheap and effective in the studio.
Other stuff:
lots of things on the MPEX web site. Not sure what, if any of this stuff is available in Europe, but but it might give you some ideas.
(Usual disclaimer -- I don't have any commercial relationship with anyone I linked to.)
