You started out by saying you don't like vintage machines and that you were on a tight budget. You might consider looking at this
http://www.quiltingboard.com/vintage...ml#post5340842 and scroll to post #725. I purchased 2 of these machines for $100 and $75. They are metal parts which is by far better than any $100 plastic parts machines you can buy new. JMHO
But, post #725 is worth looking at.
