Summary: I recently purchased a Canon 430 EX flash on Ebay. The flash I received was like new, but auctioned as a used unit. There were no scratches or scuffs on the unit. It was missing the box and the foot stand (a usual circumstance when buying on Ebay). Like most Ebay items it did not carry a manufacturers warranty. The Canon 430 EX flash is a great value flash for those looking for both E-TTL II and the power of manual flash control.
Summary: It works great with my Canon 50D. I recently got tired of using a cheap external flash, and since I am trying to take my picture taking to the next level I bought this flash. Great product Canon, as usual.
Summary: Whether you are a novice, or a professional, the 430EX will make life easier. Most novices won't use most of the options it has, like high speed flash sync, or the ability to control 2 slave units, but it is comforting to know you could. Rotating head, and extremely quick re-cycle times help make it perfect for the wedding photographer, or just capturing the family gatherings.
Summary: I am only giving 4 Stars because I am comparing it to my 430 EXII. If I had not had one of those it would get a 5 star rating for sure. Great flash, fast, bright, easy to use. What else can you want.
Summary: Carrying around an external flash is always a hassle but the speedlite is streamlined compared to many other models and competitors. What I really like about it is that it has opened up new horizons of what I can do with my digital camera. I use it heavily for indoor business function photography and the extra light has transformed those photos.
