Eeeeee lad, I remember those days! The Maplin catalogue and sending off hand filled in order forms by post, Practical Wireless, The Radio Constructor and Veroboard. In those days I drew brain-designed PCB layouts on 0.1 inch graph paper and then transferred the holes to copper board with a pin and drew in the traces using what Maplin sold as a special PCB resist pen but was actually a bog standard permanent marker, just three times the price. I even had my own personalised call sign, G0KIT. Nostalgia's not what it used to be!

More seriously, I've recently changed from using Eagle, where I never quite mastered the libraries and creating new footprints for the PCB, to DipTrace which is a bit easier to use and does have a free-for-non-commercial-use version if you look carefully enough at the website. I've only made one board with it so far but I like it so far.

As for etching, you can use remarkably little fluid by wiping it over the board with a sponge or cloth. A bit tedious but it doesn't take that long and I don't make enough boards to worry about the time.

I'm not sure my current CNC router is precise enough for milling a decent PCB. There's only one way to find out though and it would be a good test of my design and build skills. Off down another rabbit hole!
