Homebrew PCBs

Hi,

I've thought maybe i might reconsider building a CNC just for drilling,  
but i worry that the laser printer and toner transfer distortions will  
make it useless.
So i have printed two 150mm x 150mm square boxes on two separate sheets  
with my HP IIID and compared the two. there is about 1mm distortion.
Of course this is not acceptable for cnc drilling.

Now, i have the new printer already but still no toner so i don't know how  
bad the distortion will be with that one.

You see, i definitely will not build a CNC drill only to find it useless  
because of printer distortion.
I will not change to inkjet because it does not produce toner transfer,  
and toner transfer saves me much more time and money than a CNC drill ever  
will.

So, does anyone here use CNC drilling and laser printouts? Or has anybody  
done more experimenting with laser printer distortion and which models are  
good? The lexmark M412 did only cost 17eur and the toner will cost 50+ so  
i might still choose another printer.

thanks
