The best templates for the go pricing are here, I especially liked the business template. Whatever taste you might have and whatever color pallette you're using, you will find a great template ready to use for your site here!
This add-on is a no brainer, if you have the core plugin then you have to get this as it makes your table options endless. Along with the Clip Addon this has got to be one of the best addons I have used.
