Someone stated above they would only get the Janome Horizon 7700 for regular sewing - it was built more for quilting and has the 11" throat space, FMQs beautifully, and also has a free arm and great "regular" sewing features, so I don't get that...OH, NEVER MIND! I realize now you were wanting embroidery, too. Sorry!
Anyhow, I agree you need to figure out the problem first (but STILL go for the new machine!).
I think I was the one who brought up embroidery - just telling the OP of a couple of combo machines I found to be high quality.
I mentioned the Janome Horizon for sewing only (meaning sewing/quilting but no embroidery). If all I wanted was sewing/quilting, that would absolutely be my choice.
Sorry for any confusion.
