Any comments on the above flash guns. I need one in less than a month for shooting inside a high school gym...

Angel, there doesn't seem to be a lot of difference between the two, except the Nikon is 5 oz. lighter, recycles 1.5 sec. faster, seems to have a bit more power, and above all, is a Nikon. Better for resale later. Just my opinion and $.02. Good luck.

I don't know anything about the Metz, but I got the SB-600, loaded it with 4 Sanyo eneloop batteries and shot about 100 shots at a kids birthday party with a diffuser. Recycle times were very quick with a lot of charge left, I think. I don't know how it would do with older batteries but I am impressed with the results with a D90.
