We use something similar, but it's by Coghlan's and it's made in Canada. You can get it for $2.48 at Walmart, or a bit more at any camping store:
Walmart.com: Coghlan's Camp Stove Toaster: Camping
It toasts up to four slices on one burner. It folds flat for compact storage.
Alternatively, many of the better galley stoves have toaster/broiler features.
