i have an HQ16 on the table as a sitdown, bought it used, still learning but it is fun! It can be a sit down or can go on a frame. I don't believe the sweet 16 came out till late 2010 or 2011- As my 16 was purchased in sept of 10 and the sweet hadn't come out yet.Really good price if the table comes with it I paid 2500 for whole package with some extras.
