Well, maybe I'll start lowish and work my way up. Somewhere in the R600-700 range. Talisker and Ardbeg sounds like a goodish start. I love smokiness and weight in whiskey, which is why I drink Double Black at the moment, so those two may be a good intro what? Ardbeg on Oa sounds 'lighter' than Ardbeg(?)
The Ardbeg I had was a 17 year old and only 40% alcohol per volume. Smooth as hell, but can't find it in my area any longer. Personally I would hit a whisky bar or good restaurant and try out a few at a time. I've had some single malts that I had one sip or a smell of and gave them to my late father. Not all are good to be honest. Also, I avoid "finished in bourbon casks" like the plague. I can't stand the the taste of bourbon.
I can't drink Johnny Red, but en jou Johnny Black. That, Chibas 12 and Dimple are good "cheap" whiskeys for me. No, I'm not a snob, I just call them cheap as they are nowhere near the single malts I really love.
The last few years I've been more on the gin and vodka train, and recently beer. So I've lost touch with whisky costs a bit.
I had an ex whose stepfather owned a snazzy joint in Jhb. I used to get all the last little bits in the bottles to taste. Sometimes less than a tot, but enough to form an opinion.
