Gosh...I'm sorry to hear that you 'are having troubles with your Juki. I'm having similar troubles with my Consew and was considering trading it in for a Juki. Now, I'm having second thoughts. I wish there was a "semi-idustrial" machine out there. My Consew needs tuning constantly and is a bear to use. It would be nice to find a super, heavy duty domestic sewing machine out there that does leather.
