Ever since making the mistake of looking in this forum and reading the Strobist site , I've been overcome with a strong desire to start learning more about flash and off camera lighting. I was looking at some the the start kits offered on the Midwest Photo site. Has anybody bought any of their kits? Good, bad ? Or should I buy the bits and pieces on my own. I'm really looking to keep this as cheap as I can since I've bought an 18-70, a 70-300VR and a D80 within the last two months.
