W3 Custom Product Options

It's a bit wonky to understand at first, but the options work great and are fully customizable. The up-charges with products also works great and functions with variants so you don't have to fill up your product list with a bunch of options. They also assisted with integrating the code into my store seamlessly.

Haven't yet touched the image editor yet; excited to see how that works. But so far, this has been a great app!
