I have a sweet 16 and I love it. It isn’t picky about thread and runs smoothly. I did a king sized quilt with basically no problem moving the quilt through the machine. I don’t like the rear on/off switch, although I can just reach it from the front, it is a stretch. I put an 12” LED under cabinet light fixture under the harp, attached with sticky backed Velcro for extra lighting. Works well.
Would like a laser light for the needle position but the newer HQ frame machines have it so maybe the new Sweet 16 also has it.
It is a little pricey but I think worth the money.
