This is the one I have. I like it because it is low enough to the ground for the ages of kids I have. Some of them are really tall so younger kids can’t use them too much. It also has multilevels which I like for dramatic play in the table. I have had this one now for 9 years and love it! Not sure if it is available with your grant. I got it at a local shop, not online.
