Hi, I am new to the forum and wondering what sewing machine to buy...Techsew 2750, Cowboy 227R, or a used Consew 227. I have never used a leather sewing machine (only my home husquvarna that I am wearing out). I make purses, bags, wallets, journals, etc... things like this. I also tool on 4-5oz leather and then (hand) sew that onto the bag. It is my understanding that any of the above machines will do what I'm needing, I'm just not sure which one to buy. It's a huge purchase and I want to get the right one. Thanks!!
