Looking For Very Cheap Islay-Style or Imitation

I don't really want to say what it is for, but I would like to find a whiskey that shares the in-your-face peatiness of an Islay style, but is as inexpensive as possible. The quality of the Scotch itself really doesn't matter for the purpose I am looking for -- seriously, it could be pretty foul by itself, as long as it has the extraordinarily pronounced peat flavor of an Islay style.

I'm not sure this is even necessarily a single-malt question, since for the purpose I am intending for this it doesn't matter. I just figured I'd ask it here since I've never tasted a blended malt that was as peaty as, say, Lagavulin.

Any thoughts?
