I do not have a side port, just a skimmer that should work, but I would like to know more about the side port as I might want to put one in. I too e-mailed IPP about side ports and they have not returned my e-mail. If I do go that route I will likely go with what seems to be the standard that I see online. I will check the website, already tried it but for some reason not cmoing up on my work computer.
