I would personally not buy .net for the reasons mentioned in this thread already. Similarly, I would not have hyphens or any funny spellings in the address either. Just keep it simple, if your company is called Yahoo then yahoo.com should be where people can find about you.

Yahoo! was initially a funny spelling before people got used to it. Same with the word Google (before 1999 I would have not known how to spell that).
