Need good TextBox (for testimonials) plugin

I’m developing and/or rebuilding several websites for a client and need a good plug-in to use for testimonials. The only one that comes up in the plugin search is “Special Text Boxes” but I can’t get it to work properly (doesn’t look like my settings, and looks different on different browsers). Can anyone recommend an easy-to-use, free plugin that would be good for simple boxes to use for testimonials, etc.? This particular site is http://www.CRIGlobal.com.

BTW, what you see on the site (below the one I tried using STB, is the one that comes with WP, but the client doesn’t like it because the quote mark is backward at the beginning…

Thank you very much for any help you can give!
