as i know it is so hard to make vacuum metalizing at home
and galvanic metalization could be done but you need some dirty home
for small pcb i think it is not so useful to have some devices for making galvanic plating
actually i'had chance to test lpkf's product which is called cheap plating system but it was not cheap for home usage (nearly 2k euros)
and it is not so hard to make it
but it is also designed for using with lpkf's milling and drilling devices
so it could be hard to use at home also without that devices
