Because I love to sew and have sewn for many years, I would sew on most any machine that performed well either new or used.
Its difficult to recommend a machine without more information.
if you google sewing machines between $100 to $300 you will probably get many options including eBay and Amazon.
just mentioning it at quilt groups or church friends might turn up a real bargain.
on the plus side of shopping on line...if the machine is not too heavy...it is pure delightful to have it delivered to your door.
