hey Reggie,
etching is a type of intaglio printing, so an etching press is what you're looking for. They're not normally refered to as intaglio presses. I would recommend a printmaking class that includes any of the intaglio processes in addition to the photogravure workshop. Photogravure is a combo of two different crafts and learning a good honest wipe (the way the ink is removed from the plate right before it gets the squeeze with the paper) is not something most people learn in a weekend.
