I bought an Artisan 3000. I use the foot that came on it. It will sew up to 3/4" of leather. Not that I'll ever be sewing anything that thick. I really like this machine. I had never used one before getting it so it took me a while to learn to sew with a machine. It sure beats hand stitching.
I bought the flatbed that comes with this machine so I can use it as a flatbed or a cylinder head. I rarely have used the flatbed. It's good for large items that you need to spread out flat. For items that you need to maneuver around the cylinder is much better. http://www.artisansew.com/ Here are pictures of the machine with and without the table.
