I have never known of any web developer or word press developer that is ever happy with ANY of the DIY sites like Wix. No matter how great the sites can be.

Wix does have plugins. You can do pop ups (check out our site) and many other cool things. I would say if your budget does not have the room for a "professional" web programmer then, Wix is your best choice. I have in the past designed and programmed my own sites using Dreamweaver. Hope that helps.
