I've been looking at these machines for a while now and from what i can gather, they are excellent workhorses for heavier work. They are apparently on the noisier side but wouldn't matter to myself. Still trying to source a LSZ-1 here in Canada at a reasonable price. If your planning on lots of HD canvas (or similar), then i'd say this would be an ideal candidate for sure
ps: Tandy Leather has a model for sale also designed by Sailrite.
