Homebrew PCBs

Hi guys,

Checking back in the archives, I noticed several folks using Sprint 
Layout.  I downloaded the demo this morning for the new version I 
liked what I saw so far.  While I dearly love PCB Wizard for it's 
brilliant simplicity, it doesn't make it easy to work with isolation 
milling and it doesn't allow for "easy" user creation of additional 
components.

When I saw this product (Spring Layout), it appears to be able to do 
a lot of what i want.  It is very easy to work with (so far).  So, I 
am just asking for opinions on personal uses - any problems, 
gotchas, bugs, don't do, etc.

If someone has the full version, I wonder if you could create an 
isolation milling file (PLT) for me and either email it to me or 
post it in the files section.  Doesn't much matter what the circuit 
is (preferably simple), I will just be using it to see how easy it 
will be to create an import filter for my CNC machine.

Thanks!!!
Chris
