That is a bit pricey, but seems to be what I need. Unfortunately, I don't have the faintest idea how to build something like that.

Does anyone know if there is anything free that can do simpler configurators, like seen here?

I don't need it to have drop down menus, just a couple choices for parts, and have it update a total at the end. And some way to make a paypal invoice, or even just sent to me to review. I could manually send a Paypal invoice.
