A few months back i got the Juki HZL f600, and absolutely love it! It has a nice range of decorative stitches. It came with all the feet you would require for quilting and has a stitch setting for a 1/4" seam. It also has a speed control, a knee lift (to lift the presser foot without using your hand) and needle up/down mode. These were the things I was looking for in a machine and it is perfect! It was more expensive over here in the UK but I believe was around $1049 when I had a look at USA prices.
It has a different feed system to normal domestic machines and so it hasn't eaten the edges of my fabric at all, which is another plus for me!
