I recently purchased an LSZ-1 Ultrafeed (premium package) sewing machine from Sailrite, and I LOVE it! I first learned about Sailrite when I needed to make a winter cover for my pontoon boat. They have FANTASTIC how to videos on everything from setting up the tools and equipment that they sell to making complex covers, shelters and reupholstering just about anything. All of their videos are well produced and they explain all the steps necessary for completion! They also sell top notch fabrics and supplies and explain how to use them. I think I am close to watching every video they have made, even for things I will never need, just to learn new techniques! I have plans to reupholster my pontoon seats in the coming years, as they start to wear out. The money I spent on the machine will easily pay for itself with that one project alone, so it was really a no-brainer for me!
