I have Fast Tracks templates for On30. I use code 83 rail and the track, with FT's wooden ties looks great. Even with the templates though, the process is nothing if not time consuming. I've built exactly one turnout, though several curved and straight sections. And, seriously, you have to enjoy soldering! And resin fumes, burned fingers, etc.
As has been pointed out, it's time vs. money. I'm retired and my time is my own, but I still wanted to get trains running. I have a 9 x 12 around-the-walls shelf, so not too big, but, to date, I haven't built enough track to go all the way around. I use Micro Engineering On30 flextrack and Kato HO Unitrack with turnouts from both manufacturers.
Not to be a wet blanket, but pick your battles, so to speak. Try one, see what you think. Good luck!
