If you've got a home studio and are looking for a lighting setup, my advice would be to start with either a one light setup or a three light kit. The one light setup is easy and simple to use, and won't take up valuable shoot space. The three light set up is a bit more professional, but takes up more room and has wires etc. Look for light setups that have manual power settings on them, as this will enable you to get a larger range of dynamic light from one source. I've listed a few auctions below that I found quickly scanning through Ebay.
