Help! I'm a brand new quilter. I just made my first quilt for my baby granddaughter (Tumbling Blocks) on my Jem Gold. I'd like to do more quilting and want a machine that will let me get fancier with the actual quilting (knee lift, drop feed dog, needle down, etc). I want something with room to grow but without a bunch of things that I'll never use. I also don't want to spend more than $500 (less is better :!: ). Any recommendations?
