While A'bunadh is great, try Macallan Classic Cut if there is still any in your area. Almost all Macallan is over-hyped and over-priced, but Macallan CC is a fantastic cask strength sherry bomb at around $70-80 that handily beats out A'bunadh (which is saying a lot!)

I'd also recommend Clynelish 14 as an entry level sherried scotch. The Signatory Vintage releases of Clynelish distillate tend to be a bit more ($90-140) but are some of the best scotch money can buy in my opinion.
