Three equally wide columns?

Hello people!

I’ve just installed WordPress and are quite frankly amazed with it’s ease of use and the very smart theme-search website You’ve got. There i could sort themes after the only thing i was looking for; three columns.

But, even though i’ve noticed You’ve got a fantastically large amount of good stuff to read in all the FAQ’s for WordPress, i found it to take a while to find what i was looking for because it’s so darn big, hehe.

Anyway, i didn’t quite find what i was looking for, so i’ll just post a quickie here:

The actual question:

Does anyone either know of some theme which have got three equally wide columns (like a blog simply with three columns, looking the same) which is available at the some other site than official WordPress theme website (since i couldn’t find anyone there), or know of some easy way i can do this in the code?

Thanks!
