The last time I checked, Natchez Shooter Supply had brand new Lake City with uncrimped primer pockets for around $140 per 1000.
If you are lazy like me, you can also get once fired fully processed brass from Scharch Manufacturing. The advantage to the once fire brass from these guys is that it is already sized, trimmed, primer pockets swaged and polished. All you literally need to do is chamfer, if you wish, prime, drop powder and seat the bullt.
With brand new brass, you still need to process it. That is size it and trim it. The trimming part is what I really hate.
Other than that, take your pick of vendors for processed brass. I just got 1500 pieces from LEOBrass (I believe). It was cheap and shipping was timely, however, I got more than a few with split necks and a bunch of them were hard to size, maybe indicative of their having been shot in a machine gun with a big throat and sloppy head spacing. Still, with the ones that didn't have split necks, I resized them with a Lee full length size die and they all ran well enough.
