The biggest factor with the toy machines is the stitch. Most don't have a bobbin so the stitch is a chain stitch and pulls out easily. Inexpensive 'real' sewing machines, use a bobbin and do a lock stitch. Most of the toys have a set stitch length--which is usually quite long. I would look for a decent used machine. Often at yard sales/ thrift shops they can be bought cheaper than a toy.
