I would stay away from the Ross Engineering toroids.  Their prices of
toroids (which are substandard construction compared to the O.W. Landergren)
are more than
twice the cost for the same quantity from O.W. Landergren.

I received a recent quote of the 24" x 6" toroids from O.W. Landegren for
approx. $280 (i have to get the quote to get actual price) each in single
quantities while
Ross Engineering (who makes toroids that have a seam - pressed halves not
seamless like O.W. Landergren) quoted about the same price for a single half
of a similarily
sized toroid.  So two halves to make one toroid was approx. $550.00
