I purchased my HQ Sweet Sixteen sit down with the Tru Stitch and the overlay for the table. The overlay takes away the vibration when the Tru Stitch gets near the needle plate, and it tries to go over the "hump". I've moved from a standup longarm to the sit down setup due to progressive spine disease. I just love it! I use a small craft table from WalMart next to it when needed for larger quilts. I'm still learning to FM but just love the even stitches I get from the Tru Stitch. Have fun with whatever you choose!!
