As far as I know, the HQ16 and the Tiara are the same machine. I have the HQ16 with TruStitch and I must say that I am doing better without the stitch regulator. I feel like a bad driver when it is engaged. lol When I got mine, I saw an advertised price on the internet but decided to go with my local dealer. They were quite willing to negotiate and I got a decent price. Win-win. I did stop by another dealer close by and she applied tons of pressure (besides being an arrogant git.) She did not get my money.
