I am still trying to decide on a sewing machine purchase.... I need to be able to sew heavy leather dog collars, nylon dog collars and leather purses. I have sewing machine experience but not on the commercial machines. I am considering the Techsew 2700 or the 2700 Pro. Just wondering if anyone has these machines and what they think of them ?? I am wondering if it's worth the extra to go with the 2700 Pro , for the extra cost of $545.00 more ? It's a big investment to me right now, just want to make sure I get the right machine as with the tax and shipping cost it adds up quickly. Also, I have been reading about the speed reducers and am wondering if this is needed for this machine ? Thanks !
