Signatory Vintage is bottling a non age statement Islay single malt - distiller unknown (though I think it's Caol Ila) - under the Signatory brand. In the U.S., if you can find it, it runs $26-28 bucks and has a lot of brine and iodine.
Another iodine latent reasonably priced whisky is Benromach, Traditional. It runs $28 - 32. This would be, though I use the phrase very loosely, in the Islay style, as Benromach is in the northwestern reaches of Speyside.
The best part is both are quite good.
