:-) A few months ago I bought a Baby Lock Denim Pro. I use it for piecing and quilting and it works for both. There are a few features that it does not have because it is the bottom of the line starter machine. Luckily the store I got it from will let me trade up for the full price and I plan to do that. I would like a machine with a fast and slow speed and one that I can end with the needle up or down with a quick switch.
There is one more little detail that I never even thought of until I started using the new machine. Some machines have a bigger "step" or angle between the part that pulls off so you can get to the bobbin and the plate with the feed dogs in it. My old Singer had a smaller "step" so with the Baby Lock, I have to be careful how I feed my pieces so that it does not mess up the pressed seam allowance, flipping it up as it goes over the step. I will be sure the next one is flatter there.
Good luck finding her the perfect machine!
