I have never owned either machine. I love my Vikings and Brother machines.

I have Janome 7700 and love it. I use a lot of the stitches and will be using a lot more of them

Go with what works for you. If you really and truly doubt that you will ever use the fancy stitches, save your $$ and buy the cheaper machine that works for you. Why not? The idea here isn't to spend as much as you can, but to buy the least expensive, good quality machine with the features that you want.

Given that you said that you had a machine with bells and whistles and never used them and really don't have a desire now, buy the Juki. Then you will have extra money to buy some more fabric and batting. (and I'm a really happy Janome owner, now, BTW.--have a 7700, 12000 and an 350E embroidery machine-)

I am also a very happy janome owner. I have a light weight awesome all around 4120 which I started on and now I take it to my classes. I upgraded to the janome 11000 which to totally awesome. I say they are like cars. start with a medium and then trade the in for a better one if you want. :D

I have been FMQ for many years on my Bernina. I am still able to quilt a king size with it. Last year my friend was selling her juki TL98e for $400. I bought it from her. It is a great machine. I call it a working horse. And for that reason i got it. I didnt want to over work my bernina. Lol...
If all you will need is straight stitching i would highly recommed the juki. Make sure it comes with the free motion foot. It also has needle down option, knee down leveler, and one of my favorite is the scissor. So when you quilting in the middle of the huge quilt, you dont have to dig down looking to cut the bobbin thread. Overall, for a simple machine it has many basic option that you will need and use. Oh did i mention speed adjustment... True and true it is a working horse.

When I started looking at new machines in November I started out thinking I would buy a top of the line Janome, but after reading & researching I bought 2 Juki machines instead - the 2010Q and a F600.

I LOVE the 2010Q for quilting, it has increased my enjoyment of machine quilting many times over and would highly recommend it. It sews a beautiful straight stitch and has so much room to move your top around. I'm just getting started with FMQ but I know I will be more successful on this machine than my old one. The thread cutter is amazing and I love being able to sew fast when I want to, yet dial it down and control the speed too. And, it is not picky about thread, so far I've used Aurifil, Gutermann, Connecting Threads Essential, King Tut & Sulky without any issues.

I've had the Juki TL98Q for about 8 years...never one bit of trouble. Love this machine.

You might want to take a look at www.bradleyquiltco.com. This guy invented this table system and sells it with a Juki, at shows for $2900.00. He often has refurbished ones for sale as well, as he has people that upgrade. I don't have one, but I have played with his quite a bit at a number of shows, and am saving towards getting one.

Have fun!

P.S. I have a Janome Horizon 7700, that I use now for FMQ, and am a very happy Janome user.
