One other thing is if you don't know what your needs are do not buy a machine o f any kind until you know what you want to sew. I am not saying this to be rude or anything of the kind but trying to help you from making a costly mistake.
Go to a Head Stone maker and ask for a waste piece. The one I have is 5 inches thick and it is the best for setting stamping or skiving. You can also go to a counter top place and get scrap I have gotten both for free.
