DIY PCB making, milling or chemical etching? (discuss.tchncs.de)

Which do you prefer? I have the option to do both but milling seems to take awfully long and produces a lot of noise and glass fiber dust. It has the benefit of not needing etch resist which is also messy.

Chemical etching with iron chloride is also quite messy. First applying etch resist, removing part of it, etching etc. It is much simpler though and you don't need a CNC machine for this.

Chemical etching since I have all the photo exposure equipment and chemicals, but in reality I'll just send away for them since they come fairly quickly, multi-layer and vias are possible and the boards don't need drilling.
