I hate having to fix my browser after some new program or device installation program brings along a buddy. I use one toolbar--the Google toolbar, because it has the most useful functionality for me. Image searching, spelling check, blocking popups, email, Google maps and Google earth. You can set it up to do lots of different features in the Preferences section--I prefer that it have a few basic jobs and leave the rest to me. Some of the others just don't play nice with the browser and as you say, all of those toolbars take up a lot of space.
