I'm just getting my lighting setup started (one studio flash so far, along with the 430 and a flat panel flash for product) and I don't want to spend a lot. I see inexpensive flash units and inexpensive continuous lighting units.
Seems to me that using flash might be a bit more difficult since you can't really test till you shoot. I'm considering something like the Flashpoint units from adorama here. As well, it seems that continuous might be simpler to set up and meter since they are, well, continuously on. Britek lighting units under consideration here.
