I love the looks of the Southwind units, and I see them on Ebay for $25 to $50 for one in good shape. A restored one runs a lot more as usual. I would like to have one of the original Thermodor units, but one, if you can find it, that is in just fair condition is really spendy. If you find one that is restored (at least the ones I have seen) it will run you as much or more than the Vintage Air unit.
