will toss in my 2c -
went through an exhaustive study of which gear to acquire for hobbyist lighting for the last month or so, and ended up with 4 options:
1. follow strobist guide with a pair of lp180's + PW's and various shoe-mount speed rings, etc.
2. get a pair of 600-ex-rt's with trigger and various shoe-mount speed-rings (i.e. chimera ob2 kit or profoto 3' octa)
3. go straight to big lights with paul buff einsteins and that accessory system (including battery option)
4. go with bowens gemini 500's and their mod system (including battery option)
Sounds like you already made your decision, but just in-case others stumble upon this while doing their research: The Strobist guide is outdated and a bit biased, as far as the Lumopro flashes. If you're going for a manual only, third party flash it's a hard argument against the Yonguo 560 III. Now with the 560-TX you can control power and zoom from your flash, all for $50 plus $70 per flash. There's little point in getting PW is you're using manual only, other than wanting to stay away from third party venders. You can get a basic 2 light light setup with built in RF receivers, and a trigger that can control power and zoom, for $200.
