I have the HQ 16 with a sit down table. The main problem is the bottom tension. I usually have to tweek it about twice per quilt and everytime you use a different type/weight of thread. Other than that I really like it. I do put a small table next to the machine on each side to hold the weight of the quilt. Be sure to buy the cotton gloves with the dots on them to help move the quilt as you go.
