For another perspective, on a budget: I just bought my first sewing machine, an old singer industrial sewing machine (241-02) rated to medium heavy. It is not walking foot or servo motor - it is a high speed machine so I am getting use to it but it is sewing several layers of upholstery leather without problems - just finished my first purse too. cost was $50 on Craigslist! the ideal is walking foot, servo motor, etc but bottom line, there are acceptable machines for good prices. Do your research here then see what you can find. If and when you can afford it, go for the better machines. Good luck.
