I think you're going to have a rough time trying to find one for a reasonable price. In the past year, prices have skyrocketed. I've seen quite a few restored machines go for $1500-$2000 USD plus shipping which I think is insane.
If anyone is looking to have some leather split down (or buy some leather by the square foot and have it split), I just picked up a 16" wide band knife splitter. Feel free to contact me through my website - https://thehideshop.com/
