I have the HQ Avante and highly recommend it. Easy to use, small learning curve. They average about $9000. They come with Stitch Regulator (a must in my opinion), frame and machine. The machine has EVERYTHING made JUST for the Avante. Compared to other low-end machines that aren't. For example -- The stitch regulator for the Tin Lizzy is actually generic and is used on 6 different machines. I had a Pfaff Grandquilter that used that regulator and it NEVER worked right. I haven't looked to see if you can find them on the 2nd hand market.....but DO talk to a dealer and ask if he has a floor demo model. Our dealer provides classes once a month........or you can pay to go to Utah to take their courses (spendy!!!).
Good luck -- I think you'd enjoy having one!
