I'd guess that PCB fabrication is the 'thrill' of the hobby for a few, mine comes from the design and build, and ultimately applying power, and seeing the expected results. Occasionally, the unexpected smoke, sparks, and flames are pretty cool too. Etching and drilling a PCB is probably the least favorite part of the process, and usually the most time consuming. Sending off for boards is costly and time consuming, not real practical for hobby work. I use the Pulsar paper and a laminator, and it reduces a lot of the hassles, at a reasonable price.
Frank has a good product, and he spent a lot of time figuring out how to get results. I'm sure there were quite a few failures, before he got his paper where it is today. You should be glad he is willing to share his experience, to help you with your homebrew alternative to his commercial product. He's still going to get some business out of this, he has other related products, and there will still be people like me who don't care to draw out the PCB process anymore than I have to, even if it can be done for free. It still has a time price, and a little added complexity.
Most people just starting out, don't want to spend a lot of money at first, then they are willing to spend a little more to make it quicker and easier. I think that is why Frank is more than willing to help everyone make successful boards, regardless of the paper. He will still draw some new business out of this, even if you can make magazine paper work exactly the same or better than his paper.
