Yes, the Platinum 16 sitdown longarm machine is made by HaniQuilter for Viking. The differences are in the digital display unit is rectangular (P16) vs square (S16) and within the screen, Viking's has "fix" and the S16 has a needle with up down. It does the same function. Also, the tread holder is on the top of the machine vs the side. Which I like better... My HQ dealer left me bring my quilts to the store and quilt them to try the machine out. I loved the machine and I was saving a little every month until I could purchase one. The dealer also sold Viking and told me about the Platinum 16 sitdown longarm being made by HandiQuilter at a slightly lower price point. HandiQuilter makes you sent the payment to them and the dealer can not negotiate the price with you. The dealer could negotiate the price on the Platinum 16. I ended up making a deal and purchasing the Viking Platinum 16 with true stitch because it is essentially a HQ Sweet 16 with a different label and the price was better. It was delivered this weekend and I just love the machine and am sooo happy with my purchase. I did get the true stitch...since the dealer threw it in...thank you! I has mixed emotions on the true stitch because I tried it on the S16 and didn't think there was a difference. Well, I was very wrong. I read somewhere on the internet how to correctly use the true stitch. I didn't have the reciever close enough to the machine. Now that I used it properly...it is AWESOME!!! I love having the true stitch. It does keep my stitches consistant.
