Here is my two cents and the story of my sewing machine journey. I started with a WalMart Singer. Just something to sew canvas and light deersking together making pouches and stuff. Then I decided that I wanted something with more Ooomph. I bid on a used Gov't surplus machine online. I won and when I got it well it looked like it had been shoved out of a plane without a parachute and then laid in a salt plain for a year. so then I bought a used "industrial strength" machine locally. It had been set up to do upholstery leather and do it fast fast fast!!! It was near impossible to control and when it started acting up I had no one to help me out. It also didn't do the work that I was wanting to do now, holsters, stirrup bindings, chaps and such. It really was the wrong machine from the get go. I hadn't done a through job researching what I wanted and needed.
I talked to a few people, I read all the forums and reviews. At the tradeshow I visited with the dealers. To me an important factor was the character of the dealer and the service after the sale. I did buy a cylinder machine and I am pleased as heck with it. I haven't used it for a long time,as I just got it, but two saddle bags, a belt lining and a sword scabbard later I can say I am not sorry for my choice in machine. it has excess capability but I won't be wanting for a bigger machine in the future that way. True to form the dealer I bought from was honest and followed up on the sale with above and beyond customer service. So if there is a trade show near you go and check out who is there and talk to them. Or give Steve or Kevin a call. There is a lot of good info here too.
