thanks for the link, I don't mean to be lazy does yongnuo sell one for a bit less? If I get a cheaper one will it be less effective. I'm talking $99.99 and under. I ask because you might know offhand. If not I will do the homework

I see a YN 560 III, $90 and version IV for $99
The built-in flashes on cameras kind of destroyed the bottom end of the add-on flash market, so for a long time you were out several hundred dollars for any flash. However, it sounds like it's coming back, from some of the prices listed in this thread alone.
But unless you specifically need a flash, and know you need it, it wouldn't be my first purchase. I have one and rarely use it, and you can do a lot more harm to a picture with a flash (washing out, etc.) that is difficult or impossible to correct, compared to a picture without a flash that is a bit dark. Additionally, the high ISO abilities of today's DSLRs limits how often you actually need the flash, too. (This reminds me, I need to get better with my flash, such as learning how to control its output and not just frying everything in range.)
