Hi All,
I need advice. I'd like to set up a mini-mini-studio in my house just to take decent portraits of my family. I don't want to go all out, nor will this ever need to scale into commercial work.
Equipment now in possession: 10D, 420EX, 50 1.8, 17-40L, 28-135IS, 75-300IS, tripod and a monopod.
Here are the options I'm considering, would very much appreciate advice and guidance, as well as any other suggestions for a set-up that is reasonable and won't require permanent alterations to the house 
1. Add 1 x 550EX ($330). The 550 goes on a camera shoe, and use the 420 as a wireless slave on a lightstand. Benefits - TTL, relatively inexpensive, should be enough for my needs (?). Need lightstand, backdrop, and 550ex (about $600 total)
2. 2 x 550 plus ST-2 Transmitter kit (B&H bundle $799). Seems like kind of overkill. I assume that either the ST or the 550s can still trigger the 420(?). Need 2 lightstands, backdrop, and kit ($1000+)
3. AlienBees Beginner Bee package ($359). Includes
1 B800 Flash Unit
1 10' General Purpose Stand
1 48" Silver/White Reversible Bounce Umbrella
1 AlienBees Single Light Carrying Bag
Seems like AB is a great deal. For about the cost of the 550EX I get a pretty sophisticated set up, and if I ever do want to scale up, its very expandable. The cons are that its not as sleek as a couple of Speedlights, its not TTL (?), its a bit bulkier, and ?
Thanks in advance for any guidance
Ilya
Edit -
Add option #4 - a couple of $70 sunpack 383s that get triggered by the 420ex. That would be I guess a really basic but inexpensive option.
