VERY large text files and Snow Leopard

Sometimes I need to work on EXTREMELY large text files.  200-300 megs or more.

My favorite text editor on my MacBook Pro is TextMate.  However, TM chokes on very large text files.  Even ones around the 100MB mark.

Is there a text editor that can handle such files for Snow Leopard?  

Thanks!

Solution:

Vim.

The one true editor.

And this: Open big files and work fast (from vim.wikia.com)
