lol - if you intend to have a website over the longer term - which most do you should consider external CSS. If you want to make your site primarily formatted using CSS then take the time to learn how it is done. It does take some time to learn how to do it though.

There are are a number of cross-browser issues that exist but it is really quite easy to learn how to get around them - there are some hacks to get IE to behave, and this does mean a form of mental shift in terms of design, but eventually you will discover how to overcome crossbrowser issues and fully realise the benefits of CSS design.

Some will say that it will enhance SERP performance, but in my experience it is a myth. When done correctly it will improve accessibility, but if you add ids to many html tags you will achieve this also.

CSS based design will mean that your site will be ready for WAP and other technologies that will emerge.

For this reason, at the very least one should consider CSS for design. I use it and while it pains me to say this - it isn't necessarily for everyone.

For a short term benefit you need to consider whether this time couldn't be better spent generating quality unique content or building quality incoming links.

Over the longer term you will find CSS pays off.

Good Luck which ever direction you take
