I purchased a Sailrite Industrial machine approximately 3 years ago and have been very happy with it. Their customer service is awesome. The machine goes thru everything i have asked it to do - Heavy canvas, heavy denim, strapping material, seat belt strapping to name a few. It's worth going to their website to check it out. Lots of information and how to videos and you can actually talk to a representative. They have been in business since 1969 and actually cater to sailboats enthusiasts but have branched out to all kinds of DIYers. Very well priced and I'm glad I made the purchase.
