Flickr Users

Ok, I have a question for all you Flickr users out there. Is it worth it to upgrade to the pro account? I just have the basic for now, but am plan on using it somewhat as a gallery of prints for my photography business.

I know there are other hosting sites out there, but honestly all I'm wanting to know about right now is the merits of upgrading my Flickr account.

You can see what I have on there so far here.
