Hello all! I'd like to introduce myself. I'm extremely new to leather work and vinyl work. I work with the USAF as an Avionics Technician on the B-1, F-16, B-2 and various other aircraft. I have a healthy background in electrical and computer engineering and maintenance. Currently I live in Japan, and I was lucky enough to come across a very rare care in the United States; an R32 gtr. So far, the car seems to be in good condition, even the interior is very nice for 25 year old car. It does have some cosmetic problems, and of course I want to do a custom interior retrim. I'm completely capable of trial and error, and taking my time with especially large projects such as an interior retrim. So I've been doing as much research as I can, and I decided to make an account here to get a first hand opinion from you guys. Currently, I've researched about the most prominent walking foot sewing machines, since I'll mostly be sewing vinyl. I've heard of the headaches that are solved by using a walking foot. I looked for pricing on the singer 111 series, and noticed that most of the pricing with motors and table almost always equal the price of a brand new Sailrite LS-1 basic. I've seen a few singer 95-15 around sewing leather, but how well does it honestly work with folded layers of vinyl and foam? I feel that it's a bit incredible that most of these older sewing machines, or general "used" new sewing machines are over 800 dollars. I feel that 600 USD for a brand new LS-1 is acceptable, but I was wondering what other machines I could use with heavy automotive / marine vinyl. Specifically, some allsport 4 way and some thick carpeting / foam padding. What other machines can you think of that don't break the bank? I'd say the main reason i'm looking for a ~600 maximum is because I would pay for someone to take the time and ship it to me (ie: paying extra for your efforts, plus the shipping cost). Of course, if push comes to shove, if anyone is in Florida, I can get one of my buddies to pick it up and ship it to me. What are y'alls opinion on my machine choices?
