The pin feed is just like it sounds. A pin sticking up. Accufeed is a Janome feature. a built in walking foot - kinda. The machine system has several different feet. Regular sewing, open foot, stitch in the foot, 1/4" foot. You can buy a regular walking foot for the 1500. I like the pin feed when applying binding. However, I really prefer the Accufeed system on my Janome 6600.
