I use bitrates of around 1000.

B-frames are even enabled by default, and I use them with lavc as well
much of the time (fade in/out looks terrible otherwise).  Same for
mpeg_quant, and 2-pass.

Believe me, I've tried.  I'd really love to find a video codec that
compresses/looks better than lavc, even if encoding does take 10x
longer. Unfortunately, every source I've tested (mostly NTSC DVDs) shows
the opposite.

lavc is absolutely incredible on animation.  *cmp=2 qns=3 2bframes,
etc., and you can get great quality animation at very, very low
bitrates.
