I have the start right/juki combo and love it. FYI - Grace has realized the gear teeth were an issue and redesigned them. I had the old ones and when I called few weeks ago they gladly Fed Ex'd me not only a new one but all 3 new ones for free.
I have never had a problem of the carriage rolling over any of the joints and no skipped stitches however I have only had mine since June so that may be an issue they corrected as well.
I bought from kathysquilts.com and the set up also included the speed control, pre-made set of leaders, lamp that clips on carriage, pins, side clamps, etc. All I needed to get started was thread and a top. PM me if you want pictures or any info on the combo. I have since purchased the stitch regulator but I was so used to doing table top I've learned to control the stitch length so probably could have lived without.
If you go to youtube.com and type in grace start right you can see a number of videos of the company setting up, using, etc.

you might want to join the grace frame yahoo group - they have a database of items for sale by users.
plus you can search previous posts as ask the group how they feel about their frame.
i think most feel they got exactly what they paid for and are fine with that.
i would adhere to the throat size and weight limitations that the grace frame states to avoid issues with further breakage of parts.
