Homebrew PCBs

I'm considering getting an H200 laminator and have a couple of questions 
for those of you who have one:

* If the mod is done to allow it to handle the thicker boards, will 
still work as a standard laminator after the mod?  In other words, can 
it still handle doing normal lamination of thin paper items (hot or cold 
lamination) after modification?

* When doing two sided boards are there any particular techniques that 
work better than others to get the two sides registered with this unit?

Thanks,
Dennis
