For leather sewing there is nothing that compares to an industrial walking foot machine (they are even handy for stitching multiple layers of canvas). It only stitches a straight stitch, but the power is not matched by any other machine. With a size 22 needle I can stitch two 12oz latigo pieces of leather with no problem. The only downside to an industrial machine is the space factor. You need a dedicated space to set it up. No storing it in the closet when it is not in use. And they weigh a friggin' ton!

Funny little side bar: I have been sewing on an industrial machine for over 35 years. When I am on my little domestic machine and get to a corner, I always move my right knee to the right and can't figure out why the presser foot doesn't lift.

Back to the OP:

In my opinion (and the opinion of many others) Husqvarna/Viking makes the best domestic machines around. I did a little search and found a dedicated Viking dealer in Alliance, NE. Special Stitches is a fabric shop about 35 mi from the 69347 zip code. Janome is also a good machine. Pat's Creative Stitchery in Hemingford, NE is an authorized Janome dealer.
