The 12V Proxxon will be fine to drill PCBs, but it will begin to
struggle for holes above 3mm diameter.
If you drill many very large holes the IB/E is a better choice, it is
mains powered, but also more expensive.
I initially bought the IB/E for PCB work, but soon got tired of taking
it out of the stand to use for other tasks and got a cheap 12V
micromot to leave in the stand and drill PCBs with.
Generally Proxxon makes quiet tools with precise ground steel collets,
while dremel makes less precise, louder but more powerful tools.
For PCB drilling Proxxon is the better choice.
I don't have the stand, I made my own.
