One of the biggest problems with hand-etched, milled PCBs and small parts is the lack of solder mask. Solder mask goes a long way towards preventing bridging and keeping the solder where you want it. The resolution generally won't be adequate for small parts either. The most reliable option is a commercially produced PCB.
