For new batteries you may look at CALB, nice chemistry (less flammable), good power levels, but heavier than say the Tesla batteries.
Cost wise you cannot do better than converted OEM packs, Tesla, Nissan, or Chevy.
There are also LiPo style batteries available new, I don't have experience with those, there is an electric drag racer who sells them on here.
