Nikon J1 or V1 need your advise.

I went with the J1 b/c of the built in flash.  Like a prior poster, I will not carry around an external flash no matter what it costs or how small it is.  I ended up with the 10-30mm, 30-100mm, and J1 all refurb's for under $400. Very happy with the system.

- I am about to go to a birthday party in about an hour.  Instead of my D7K, I will take the J1.

- Next week, I am going to SF on a business trip. With only a few free hours Thursday night, it isn't worth carrying my D7K, heavy lens(es), and flash with me.  The J1 will fit nicely in a small case in my briefcase.  It is going on the trip.
