HELP WANTED!!!

[caduceus]

As some of you have already heard, my guestbook host has now finally lost the last few marbles it still had.
My guestbook exists, I can read it, I can click on the "reply" button - but what I type no longer appears. This is a shitty situation, and it calls for desperate measures. Like, kicking Dreambook There, I said it's name! :P and moving on.
In the meantime, I have taken down the link to the old guestbook from my site. Meh!

I need your help to find a new guestbook host for my site.

So, all of you lovely people who have a site and use a guestbook, what do you use, and can you recommend it?
I'm not asking much: I want a clean, simple design, preferably customizable to match my site's colours, and easy handling.
Additional goodies would include some measure of security to prevent robots and non-human spammers from cluttering up my guestbook, and e-mail notification that allows me to approve every entry before it's posted.
And, since I am a poor student - it has to be a free service. ;)

Can you help me?

Thanks in advance! *muchos smoochies*
