Hi from MD. I started quilting on a Janome DC 1050 and it was a wonderful entry level machine. I used it a LOT as I fell further in love with quilting to the point I realized I wanted to make bigger quilts and wanted a larger harp space and more features. In 2015 I tried out my niece's Skyline and loved it, but it only has like 7" harp" . I wanted the 11" of the Janome 8200.
If you still do a lot of sewing, I'd say buy the biggest, best you can afford after visiting dealers. You'll get a feel for different machines and one will "call out to you" and you'll know. You also want to feel comfortable with the dealer because good service is king. I'm a Janome girl but I also like Brothers. Stay away from Singers built after 1970. They're plastic and don't hold up.
