I think the HQ 16 is one of the machines that counts every stitch so you may want to know how many this machine has so you know how much it has been used. Does this price include the leaders as they can be expensive to replace. Also HQ16 has a video that comes with the purchase so is that included or is that something you would have to call and order? Lots of good info on it. Also, something to keep in mind when and if you do buy this the tracks on frame are held down with 3m double side sticky tape so have that on hand before you pick it up or you wont be able to play when you get home. Hope this helps a little. Let us know if you purchase this.
