My Juki TL98QE has a 9" throat and I haven't made a quilt that I haven't been able to quilt on it.I usually make twin to queen size quilt, only a couple baby quilts.
The bobbin holds more thread than any of my other machines. It only straight stitches,forward, backward, needle up/down by, push button, fabric never gets sucked anywhere. I have an indentical one for back up, and 3 other machines if I want to do anyother stitches.
The Juki works great for me. It has no plastic parts and is a workhorse.
