I have the Babylock Quilter's Choice. Love it. Only wish the throat was bigger.
When looking for a machine, I would also look for something with the largest throat you can get, possibly a stitch regulator, bobbin empty warning light, top loading bobbin?, feed dogs that drop, a walking foot, an open toe or closed toe darning foot (depending on your preference), knee lift, self-threading...
Try the machines and see if you like them.
