Agreed. You cannot go wrong with a Workforce 1100 with CIS. They print wonderfully on card stock. Here is a 3D Dungeon I built for my son out of generic Walmart cardstock.
(sorry the picture is blurry, stupid phone camera)
I have printed on JPSS, Jet Opaque, Cardstock, you name it. My wife also runs about 200 pages a week for school. It is a great all around printer and fits my needs just fine.
