I don't know if you are still machine shopping, as I see this is over a month old, but I bought the J6300 last June online. I called the vendor and talked about the machine, and as I had already purchased several machines from this company I was satisfied in this purchase also and went ahead, even though to me this was quite a bit of money. I love it. It came in pristine shape, the dealer IS a real Janome dealer and you have a warranty with them. Sew Vac Direct in College Station Texas. I have had such good experience with that seller. Anyway, as to the 6300. It sews through everything nicely - I have pieced two quilts, sewn a shirt, a quilted pillow case, a double sided quilted lunch bag lined, and several other things, and just completed two quilt tops and am FMQuilting them now. I love the machine. I have another machine with lots of lovely deco stitches which I hardly ever use, and with alphabets as well, so it's fair to point out I have those if I need them. However, I would recommend the 6300 highly as an only machine anyway. It is of course, a flatbed machine, so no free arm, which might or might not make a difference to some people. I learned in the old days on a flatbed machine, so I can do cuffs etc. without a free arm, though a free arm is handy. Features I love on the machine are the knee lift and the thread cutter, although I only use the thread cutter at the end of seams because of the short little ends. I also of course love needle up/down, but that's pretty standard now days.
