Hey Theresa - a dw788 is a Dewalt 788 scroll saw. That is the saw that I presently have. Have had it a number of years - got it when my kids were small - didn't have the time or patience back then. Especially when I couldn't figure out WHY I couldn't seem to cut a straight line with it. Grown kids, more patience, and learning why it didn't cut straight and how to cut straight - here I am now learning to use it.
