I use Seamonkey.
It works well for most websites.

I just upgraded to version 2.0b1.
It seems faster even though I'm not using an optimized build.
It also has noticeable bug fixes, but I have noticed two new bugs. Mail and newsgroups are not viewable unless you select the "modern" theme and relaunch. Also it seems to have done an incomplete job of importing settings from version 1.1.17.

The nightly builds (that will eventually be 2.0b2) have fixed the bug where mail messages aren't displayed in a separate window in the Classic theme (I reported it shortly after the beta release). Additionally, they've given the Classic theme a Mac-friendly makeover to blend in better with Leopard. I think 2.0 is going to be a banner release for SeaMonkey.
 
If you want a stupid small browser that actually still manages to show most things decently, there's always dillo.

Lol, Dillo. I played with that some on Ubuntu.

Camino is pretty cool. Like a native firefox, or something. I use it when Safari won't display a site right, or I want another whole browser open instead of just a window.

Thank you for the update.
I have run into another problem with Seamonkey 2.0 ( a nightly 2.0b2 build).
I can't send any email. I always get this same error.

"Sending of message failed.
An error occurred sending mail: Unable to authenticate to SMTP server smtp.charter.net. It does not support authentication (SMTP-AUTH) but you have chosen to use authentication.
Uncheck 'Use name and password' for that server or contact your service provider."

I have no trouble sending mail with a G4 optimized build of Seamonkey 1.1.17 from http://www.rpm-mozilla.org.uk/builds/seamonkey/ with what seem to be identical settings.

edit: There is a workaround for this:
1: In Seamonkey 2.0, type "about:config" (without the quotes) into the URL bar and hit return
2: look for mail.smtpserver.default.auth_method
3: change its integer setting to 0 (instead of 1)
4: restart Seamonkey
