Ardbeg 10 year and Laphroaig also in 10 year are both very good islay whisky's for the money.
I picked up several of each during a local holiday sale at about $35.00 each.
On another note I went crazy and found 4 bottles of Belvenie tun 1401 batch 3 sitting on a store shelf.
Bought it all, but have not opened any to try yet.
I hear it's wonderful whisky.
