I had a HQ16 with a pcquilter from 2011 through 2018. Loved the setup and got it used so the price was right. The pcquilter worked well, but the old xp computer it was on was on its last legs. The HQ16 was not stitch regulated and the pcquilter didn't require it. Newer robotic systems all require stitch regulation, and I didn't want to change the HQ16. I do recommend Handiquilter, though, as I had zero problems with it in the 7 years I used it. DH maintained it for me, but all it ever required was cleaning and a bit of oiling.
It was replaced with a Q'nique 21 with Quilters Creative Touch robotic. I like it. I got it in May but 'stuff' has come up, so I have only used it sporadically, but it works well.
I will suggest that you look at used LAQ and computerized quilting systems because the difference in price from new to used is sometimes astounding. Also, make sure you can test it while it is set up so you know that it works.
