A New Look For This Blog

I was checking out some new themes the other day and wondering if I should change the colors or theme of this blog.  The current blog’s theme is actually a custome one.  I found a simple older theme and kept modifying it until I came up with the theme I’m using now.  I kinda of like it the way it is now because of the fast simple layout.  However I also realize that others like fancier themes and looks.  So what do you think?  Should I keep this layout?  or Should I install a fancier one?  If you are a blogger and like a certain theme for wordpress then feel free to also include a link to it in your comments, I will take a look at it.
