I also recently built an ergodox and it is definitely worth checking out. As far as assembly, I didn't bother with a magnifying glass or anything. Just my phone to act as a good bright light source and everything went smoothly. I would recommend extra care with the diodes as I lost a few opening the packaging and had to get extras to finish the build.
