I've done it. It's not super easy, and you have to be really anal about getting the etch resist looking right before you actually etch. I'd reccomend sending your boards away to a place like AP Circuits (http://www.apcircuits.com) or one of the other board houses to ensure you have nice traces. If you use a service like Olimex you'll also get solder mask which is _very_ helpful when trying to solder. Guessing that you're from .sg, these may not be the most feasable, but there should be someone locally to help you!
