Second SB700 or SU800?
I'm using a D3100 and just got the SB700 today, just playing around but so far I love it.
I want to do off camera flash but don't want to use a 30' TTL cable.
Would it make more sense to buy a second SB 700 flash and use one as a commander and one as a slave, or buy the SU800 to use to trigger the 700 I have now?
SB700 is $329
SU800 is $259
I will be shooting portraits almost always.
Thanks for any help!
