Sharon,
I just got a Q20 about 2 weeks ago and absolutely love it. I am surprised you are picking up your Q20 and it isn't being set up for you in studio. Putting the table together is challenging, and both the table and the machine are heavy. I think it can be done without the dealer because the directions are clear, but you will need help and then getting rid of the giant boxes will also be a little challenging.
Nevertheless, I am pretty confident you will be very happy with it. It is not a complex machine like the 830 (I have one of those too and love that, but apparently you did not have the same experience). There is some information on the internet with
videos, etc, and you can download the
manual, which is different from the instruction book that comes with the machine. I have some blogs about my Q20:
The Q20... and
My own quilting retreat, in which I show some of my practice pieces.
The things I love about it: The stitches are beautiful and even. If you tried quilting on the 830 with the BSR, the BSRs on this are like professional tools compared to a nice tool to use once in a while. BSR1 works best for free motion movement; BSR2 works best for ruler work, and BSR3 is a basting stitch, then there is the non-BSR mode. Ruler work is really easy with it; You can really see what you are quilting and it will slow way down or go really really fast with ease.
But it requires a little bit of practice.
Best wishes...let us know how it goes.
