I currently own a 580 EX II and 430 EX II and I'm thinking about adding some continuous lighting. Honestly though I really don't know what to look for. I've seen a lot of light kits on eBay that are pretty cheap. Could someone recommend a product. Possible applications would be macro, light box, product photography, maybe some portrait. I'm also looking to buy some stands and umbrellas for my speedlites. Right now my budget is about 200$.
