Can you help me understand the difference between the juki dnu1541s and the juki du1508ns?

Bringing this thread back to life.  Which of these models could someone recommend for making leather jackets?  I use an .8mm and a different 1mm cowhide mostly and will start to use horsehides soon.  I also will run some horween veg 5oz or less through it some times.  Jackets will be the primary and my vintage Adler 167-373 has trouble getting over thicker seams.

I believe that the Juki LU-1508 series may be too heavy duty for the thinner leather you want to sew. This series is beefed up in order to sew into denser and thicker stacks of material. The DNU-1541(s) is probably a better match. It can sew over thick seams and has a thread range more suitable for thinner and softer leather and broad cloth, or denim.

Now, if you will be sewing leather or heavy canvas jackets, with flannel, quilted, or fur linings, the LU-1508NH is the better machine. But, it may eat thin vest linings.
