Geocities - always up (plus) has ads (con) can't use scripts for forms, password areas etc (con) easy to use (plus)

Angeltowns.com, haven't used but they have no ads or site banners on your site, you get enough space, can store scripts etc too.

I used Geocities and only moved to my paid host when I required more such as scripts, mail features, improved log features etc.
