I was considering the Zeiss 50mm 1.4, but Ive read that the bokeh is horrible...
Where? Ken Rockwell? I've never used it but from the pictures I've scene it looks fine.

My favorite lens for bokeh is the Pentax 50mm Super Takumar (yeah, I know this picture I took is slightly out of focus, but we're talking about how well the out of focus parts look anyway). This was shot in a Hookah bar in Astoria. I love how the background slowly melts together into rich colors.
