Try getting the Vivitar 285HV used on ebay--it will save you a few bucks. Otherwise, you can buy a less powerful Yongnuo YN-460 or YN-462 on ebay for about $40 with free shipping. That might give you enough to buy a lightstand, umbrella swivel, umbrella, and remote triggers if you shop around. Learn how to light and the quality of your images (no matter how good they are now) will improve dramatically.
