I, too, have the Brother CS6000i and it is great! Very lightweight but works well in a cabinet. Without the cabinet you need some rubber under it to keep it from sliding around.

I third the recommendation of the Brother 6000i. It is a very nice machine, and can't be beat for the price. You can order it from Wal-Mart online for $146.xx with free shipping to the store if you want. I LOVE mine.

I love my Pfaff Passport for taking to classes and sewing groups. It has the built in walking foot, needle down, tie off stitch, numerous needle positions and over 70 stitches. Fifty of them are decorative. It sews like a dream.

The Elna Lotus is a wonderful machine.

I saw an ad foe a Bernini--$140. It is supposed to be very light weight. Any one have more info about it?

I have the Pfaff Passport 2.0. It weighs about 13 pounds, has 70 stitches. It also the IDT (Pfaff's built in walking foot). Several the women in my quilting group have them. Its about $500-600 depending on where you buy it. Some dealers include the slide on extension table, it comes with quite a few feet. I really like it. I have a full size Pfaff Quilt Expression 4.2, too.

I have a Brother 9000 SQ that I got from Wal*Mart. It is lightweight with lots of stitch patterns and costs about $200.
