My cousin just got a Janome Horizon 7700. She brought over her firt queen sized quilt that she quilted in only 5 hours. She had even given some(5) of the grandchildren time to learn to do quilting .Even the 7yr old done a marvelous job. I would say go for it.

Congrats, on your new machine, I just took my 7700 out of the box last night. I sewed till late last night and all day today. I previously had a 6500 and loved it but put hundreds of hours on it, I kept it. But wanted to get the extra throat space and extra lights. So far I love the 7700. hope you do to.
