I'm not the biggest fan (need to try it again) but its excellent value, and a lot of people seem to like it, the Aberlour A'Bunadh

Then you have the Glenfiddich 14yr Rich Oak or 15yr Solera Cask which are both excellent in both value and taste
If you are feeling brave, the Caol Ila 12, an excellent entry to Islay malts with Peat and Smoke but quite light

This going by the 18, this is very laid back for an Islay
