I have both the Janome QC 6260 and the new Janome Horizon.
I love them both.
The 6260 is a workhorse. She'll sew through cement if you ask her :) It doesn't have a walking foot but I put on an aftermarket one and use it almost for everything. It does great FMQ but has a 6 1/2" harp space so that does make things a bit tight.
The Horizon is a dreamboat. The computerized menu is so easy to use because the dial on the front can be used to "scroll" through the menu instead of hitting a button a hundred times until you get the stitch you want.
It comes LOADED with every foot you could want.
It has a free arm and an extension table.
It has hundreds of stitches, and alphabets too.
It does have the built in walking foot, and it works very well.
It has more needle positions than you'll ever need because you can move it from the far left of 7mm to the far right.
It's a cinch to thread. You can see the bobbin through the clear plate to see if you're low on thread - without having the false alarm "bobbin low" alarms that a lot of computerized machines will give you.
It has the built in thread cutter. That's great for piecing, but I don't use it in FMQ because I prefer to bury my threads.
The one and only thing I'd change on the Horizon is the knee lifter. It's too far to the right to be comfortable for me to use - so I just attached a wad of cardboard to the arm with duct tape and now I can reach it fine.
AND the 11" throat is a dream to sew with.
I even use my Horizon on my Inspira quilting frame and she does a great job.
When I was doing my shopping, I did have the Husky/Viking 9" throat on order, then changed my mind to the Horizon. I've never looked back.
LOVE, LOVE, LOVE it!
