The most satisfactory method I've found is to use dired like this:

Normally press 'a' on a subdir which replaces the current dired buffer
with the buffer of that subdir.

Use 'enter' when you actually want a new dired buffer, sometimes it's
useful

Use 'i' which inserts the subdir into the current buffer when you know
the directory listing will be fairly short.  To remove these when
you've finished use C-u k next to them.
