What are you end needs? Finished product, research and development, hobby learning, work?

I want to hit print and get a single sided board in 30-60 minutes with 10/10 T/S. For a reasonable cost, and without a lot of hassle. This seems like such a simple problem to solve.

Again... Voltera?  Seems to meet your needs.

The only time I've seen them used in a worthwhile manner is for complex RF slartibartfast stuff.

Anything else should be simulated, and even the EM stuff should be run through an EM simulator before cutting copper.
