I bought a used HQ Avante several years ago. I was afraid I might be buying someone else’s problems, but I haven’t had any of my own (regarding the machine) since. I find the HQ people very helpful when I do have questions. Pro stitcher is a nice option and quite expensive when purchased separately. It all comes down to your comfort level buying used or new. Also, some folks don’t like learning the pro stitcher. The machine and frame will still work well without it.
