Well I have been debating between going with either a couple of : http://www.calumetphoto.com/item/CF0502K2/ with a battery pack and ac inverter Or a couple of: http://www.mpex.com/page.htm?PG=Strobist%20Kits (PC kit 1) I would also get cybersync transmitters for them. I do a lot of outdoor shooting especially now with the ski/snowboarding season I'll be doing a lot of park shooting. Then I also do plenty of portraiture indoors. which would be a better solution for the long run, yes I would spend more on the calumet for now but will it pay off in the end? Thanks for all the input.
