Flash recommendation for Nikon D3000?

I have a Nikon D3000 and need a flash for an upcoming wedding. I have all the other accessories and lens… Just not a flash. My bulti in flash just doesn't cut it indoors… I'm looking for something thats reasonably priced and swivels.

The SB700 is the current entry level Nikon dedicated flash unit.
If you can find an older SB600, you can save a few dollars, but they were so popluar, it is difficult to find any for sale. Most people keep them as a second flash when the upgrade to a SB700 or SB900

If you have not shot a wedding with flash… Be careful. Rent one from your local pro camera shop and practice before in some kind of event that is similar to where the wedding is going to happen. This is suppose to be a once in a lifetime event… And messing up the pictures because of lack of experience with make a dent in your relationship with the bride and groom.

SB-700 at the very least. Get 2 sets of high quality rechargeable AA batteries. I like vapex' 2900mah batteries.
