I've been quickly building up my OM-D E-M10 system, have finished with lenses for now and next on the list is a strobe. I see that I can easily find a used FL36R for $100-150, which is a lot less than a new FL600R ($300) or the Lumix version ($230). I also have read many complaints about FL36R recycle times due to the 2-battery design. Paying the extra money is not going to kill me, but I don't use flash all that much so going with the FL36R is tempting. I'd like to hear both from folks who are 100% satisifed with the FL36R and those who had the FL36R but upgraded to the FL600R.
