I didn't look for anything like that. In fact I did not even use
bzr-svn though it is available. It is a little clumsy, but created a
bzr repository/branch with a svn checkout.

bzr init-repo foo
cd foo
mkdir trunk
cd trunk
bzr init
svn checkout .....
bzr add *.el

As you can see from above there is no direct integration between the
two. when I am ready to commit to subversion I cd in, fixup any
renames, and then do a typical svn commit.

It is not the prettiest way to do it. For subversion there is a real
plugin to interface directly with svn, but the approach above does
work, and it is fairly easy within a limited scope.

In fact using bzr itself is quite easy. Where I ended up scratching
some repositories is the process of finding a workflow that fit my
development style - not how to use the features, rather which features
to use, and how they fit into an overall scheme of development.

I hope your experience will turn out to be as positive as mine.
