I have the 39 inch. After 30 years of doing Product work i find it one of the best investments I've made.Heres the one I have. I got to get rid of a ton of crap I didn't need anymore.If you want in camera perfect isolations.This is it. it requires 4 lights. One under,One behind and 2 for the product. Then .......Of course some skill to balance them. not recommended for Newbies but it sure beats what we had before.About $500.
