I went down this road, compared and contrasted both models. Nick-O has both machines as well as his house brand of the 1508. I went with the Adler, phenomenal machine. Nick is one hell of a guy, bought several machines from him! The rebuilt Adler on new stand, motor, speed reducer and all the right feet, feed dogs and set up! I wan to say around $1,100. He can also convert ove frm 135 needle system to the 190 if preferred! It runs 207, I stick to a 138 with mine!
