Thank you for your help. I have been doing alot of resurch and gave the folks at alien bees a call and they were very nice and helpful and I think I am going to go with Einstein 640 WS light with portable battery pack. I had read some reviews online about softboxes falling off and they assured me that the problem has been corrected and I did like the 60 try it out period. I also do use a sekonic 358 meter but hard to to with one speedlite. It is limited in what it can give me power wise. I also like the fact that I will have AC/DC power for any situation. Other lighting systems were just way to much in cost for waht I want to do and not all were variable powered. Thanks again.
