Guestbook for wordpress 2.6.2

Is there any guestbook plugin that works on WP 2.6.2? I used DMS guestbook before, but after upgrading to 2.6.2 it′s no longer in use. So my question is once again, Is there any guestbook that works for me?
Btw at the moment I use a guestbook template, just a commentssite that is.. it sucks=)
