Gee - I’ve never heard of Sailrite sewing machines so I don’t feel competent on making comments. Having somewhere to take a sewing machine when things go bump in he night is always a good thing. Lots of repair people won’t even work in mechanical machines since there are so many computerized ones in the market. I’m not sure how heavy the fabric is you want to use but my older machines have no trouble with many thicknesses. I would suggest you take a look around before making your purchase % take fabric you want to use when you shop for maybe an older machine to test what it can sew. I’m just suspicious of names thst I’ve never heard of and I’ve heard if most, even the older Singer clones. And as a P.S. I’d never purchase any Simger from the last 50 or so years - they are very plastic inside. Hope maybe this helps a little.
