2d for newbie ?

Please help. I'm going around in circles searching for a simple,
affordable 2D cad/cam pkg. for a 2 axis plasma cutting system I am
building. it is my second one and includes ball screws and a nice
little hardware pkg from Camtronic with servos and gecko drives. It
seems like most the real snappy cad/cam stuff is all 3D. So far I
have been using Corel draw. ( no snickering please ) Vector was
recently suggested. Any suggestions will be very happily taken.
Please respond before I dissappear into ever deminishing circles.
