Hi Emma, I made a little search in Internet for you.
I am Italian but I know some "good" shop there in UK.
You could buy Laphroiag Quarter Cask @ Oddbins for only £25.99, a real bargains! see here for more referencehttp://www.oddbins.com/products/productDetail.asp?productcode=13100
The taste is "sweetpeat".
Or, maybe, you could buy Springbank CV, around £30, it's not from Islay but from Campbeltown (near Islay). It's quite similar to Islay Malts but it differs having less peat, more similar to bonefire by the sea, little salty and seaweed; very good indeed.
Let us know what you buy and if he likes it
Choice on you now
