I started out with a Bernina 750QE and traded up to a 880 within two years. I upgraded to the Plus option a few months ago. I've never looked back. I have two complaints about it: the stitch plate has a brushed look to it and it's very hard to see the 1/4" mark and the touch screen is so sensitive that when fabric brushes it, I find settings changed. Other than that I love this machine. As I grow, it does what I need and want. Embroidery is beautiful. The harp space is big enough for me to quilt a queen sized quilt. Service on my machine runs less than 100.00. I've never had an issue that wasn't caused by user stupidity. I will say that the manual is less than stellar. YouTube has been my friend.
Now, I will confess to being a tech junkie and the Babylock Solaris and Brother Luminaire fascinate me, and I'd love to get my hands on one to try it out and see how it compares. But the cost........
