I like the Islay's as well, but every man has his own taste.

You could try: Glenmorangie 18yo, Scapa 16yo, Highland Park 18yo, Balvenie, Glenrothes 14yo, Springbank, Longrow, Oban, Isle of Arran, Ledaig, Bruichladdich

I do't know the prices in the US, but a 100 dollar window gives a lot of choice.
Once you set out on that journey, it can take you the rest of your live.
