Yeah, it's more a question of getting a small secondary body and trying to recoup a few $$$ towards lenses.
In order of necessity:
Needed zooms: 24-70, 70-200, and 14-24.
Needed primes: 35, 85, 50, 24.
I've started in the middle for both of these progressions, just based on opportunity. The 85 and 70-200 were available at a decent price. With full frame, a 24-70 must come next, and then either a 35 or completion of the zoom kit.
