I have used the 1200's for years...they are solid....no monolght is put together as solidly as these. They never fail either.....these are a tremendous buy for the money. You can't wear them out. I don't know the seller(but he has great feedback) but the product alone is worth a bump! Way better than the Alien Bees which sell like hotcakes...I know, I have them both.
Bump for great material. I've already blown my budget for the year... still using three old WL heads.. one WL5000 and two WL10000's. I really trust this brand.
