the juki TL98Q or the Janome 1600p -DBX
please help one more what about the frame's i am looking at the grace machine quilter pro or the grace mini pinni no baste machine quilting frame i like the way grace machine quilter pro is set up but i know nothing about eather

I have a Juki TL98E and love it. It has the needle down function, the thread cutter option and the leg lift option. I have done quite a few quilts on it (various sizes) and it is a workhorse.

If you machine quilt . . .having the ability to lower the feeddogs is vital. I don't think the Janome has this capability but I'd check. The Juki does.

The Janome has a cover for the feed dogs but they are easily removable as well. I've seen fewer complaints on my machine quilting groups with the Juki. Many people seem to have trouble threading and tensioning the Janome. There are a few different versions of both machines though so make sure you get the version that has the features you want--thread cutter, needle up down, domestic needles, knee lift, etc.

Love my Juki!
It sews like a dream have had it 5 years use it daily and it has never given me any trouble at all.
except having the light bulb burn out!

I love my Juki. I quilted on it alone for a few years and last year I got a Grace Mini Pinni frame. I love the combo. My machine works great on it and it make quilting much easier on my hands and arms.
