Thank you, that does help. I was a bit skeptical about the shimpo, but pottery is just a hobby for me, so the shimpo would do just fine with my home studio.
The Shimpo 30" slab roller is made in China by Friendly Manufacturing Corp (FREMA). Over the years it's been sold by Ceramic Supply, Axner, and others. It's still currently sold by Pottery Supply House in Canada. It's a good slab roller. I used to sell them, and several of my students and customers have them and they've been good machines, especially for the price. For a home studio it's a great choice. I probably wouldn't get one for a studio where it's going to have a lot of heavy use, though. For a heavy use studio I would go with the NorthStar Super series or a Bailey.
