We sell both the Juki and HQ Avante in the store where I work.
The Juki 2200 is a great machine with some nice bells and whistles. The frame, on the other hand, is pretty cheaply made. The bottom leg pads are always falling off. And the plastic cogs on the end of the poles don't really work. And the leaders slide side to side. When you order a Juki 2200, we sew off the machine to make sure it's working, then send you the parts, and you assemble the frame yourself.
I like the Handi Quilter Avante better. It's a little less expensive. It doesn't have as many bells and whistles, but is a very solid machine, and it sits on a very solid frame. The frame, track and carriage are soooooo smooth. The leaders are Velcro-ed on, and don't slip around. And you get someone to come set up the machine at your house, give you lessons, and service when you need it. Handi Quilter is a great company, with great customer relations.
