I have a Brother CS4000 that I got refurbished from Overstock.com and I love it. It isn't my Bernina, but it is a nice little machine, that I can use to piece while Sadie (my Bernina) is embroidering. It has about 30 stitches and there are 7 mm decorative stitches, which my Bernina 440QE didn't even have. That isn't available now but the CS6000 is and it is $149 with $2.95 shipping. It came with a full warranty. You can adjust the needle position to the right or left, and adjust the length and width of the stitches. It isn't nearly as heavy as either of the Bernina's I have or have had.
I recently won a Janome Gem Silver edition. It weighs about 12 pounds and is nice enough, but it only has about 12 or 14 stitches and they are preset. You can't adjust the length of the stitch and you can't move the needle position. I don't know how much they cost new, but I think for the money I would go with one like the Brother CS6000 or CS4000 if you can find it.
