I appreciate everyones feedback and opinions with my posting concerning what type of sewing machines others use and own for holsters and other leather projects. With the positive opinions with the Cobra models I did call Steve with Leather Machine Co. today and discussed my options with him. Nice guy, very knowledgeable. With the apparent reputation of the machine and Steve's assurance and importance of customer support I'm moving toward spending the extra bucks and placing an order for the Cobra Class 4.
