Etching is gross and fun :P I've etched a prototype of one h-bridge of Segboard's motor controller to test. I like etching because it's much faster than ordering PCBs (which takes like 2-3 days for shipping and stuff). Also etching is much cheaper. The only problem is that it's pretty messy if you're not graceful (ferric chloride stains your hands and clothes) and your board isn't the nicest looking thing. Oh well, I'm cheap and in college.
