In my classroom we have a Northstar. What I like about it is the tables on either side remove very easily, they even have handles, so you have access to that work surface space when the slab roller is not in use. It's not heavy, so you can just slide it over out of the way. What's irritating is the two tables add an extra 80 dollars or so to the price, a lot for two chunks of wood with formica on top. And if you want their heavy canvas, it's another $30ish I think. Once again, a load of money for two chunks of canvas. I don't know why heavy canvas is so expensive and so hard to find. It is a really useful item around the studio.
