I have that same machine and LOVE it!!! It is a super workhorse. I love Janome machines. Be sure to test drive it before you pay for it, but I say GO FOR IT!!!!!
I have sooo many hours on mine. I too, bought it used. The gal that owned it, passed away and I think of her often. I do lots of embroidery with it and love it.
Can you tell I really like this machine!?
