currently only got a 50 1.8 II
I'm planning to buy the 70-200 f4 later on

But before that I'll buy a flash, probably 430 II
get a yongnuo rather excellent flash at a great price
the newly release yn-565 is awesome (comparable to the 580 ex ii, but does have some better features and at $180 you are saving a fortune), but i would wait a month or so just so they can iron out any little issues
i have a yn-468 and its great, 2 more yn-560's are on the way
