The cheaper versions of that would be, for example, a Redbreast 12 (Irish) or a Glenmorangie 10. The only Highland Park that I have sitting around is an 18 year old, and I just compared them to that (again, the nice thing about whiskies is that you can put a few drops in a glass for comparison), and while they both have a little less to them than the 18 year old, they're also less than half the price. If you're feeling like branching over to the fruitier side, something like a Glendrodach 15 would be worth trying. It's not soo far off from the others, but tastes a bit sweeter and is a bit more complex.
If you're committed to smokey, non-iodine-y whiskies, Talisker is good, as noted. Maybe a Bowmore 12 (a little sweeter), or, if you find it, Ardmore or a Ben Riach. But again, it sounds more like your tastes go away from the smokey stuff to subtler whiskies.

A thing I'll note for the uninitiated here is that another nice feature of whisky is that there are literally only dozens of distilleries. There are something like 80 in Scotland. For a whisky nerd it's entirely possible to have a good 1/2 to 1/3 of them on a reasonably sized shelf. And since bottles take several years to go off, you really can have a huge percentage of the total range represented in a moderate whisky nerd's collection.
However, I love wood smoke, so I'm intrigued enough to keep at it. I'm trying out some non-smokey whiskies too; I had a glass of Macallan 12 that I enjoyed quite a bit.
The last few glasses I drank were really disappointing compared to the initial fanstastic glasses. I can't describe the tastes, but it was simply not good anymore. When too much air gets into the bottle, the Whisky can oxidize, changing its taste (usually for the worse).
I haven't attempted whisky much yet, but I believe that you trained your taste to appreciate the domain and recognize the subtleties within that domain enough to appreciate something you didn't immediately.
I say this as someone who's gotten into music genres I hated 10 years ago, forced myself to try cilantro, olives, more pickled food, and regional cuisines to a point where I appreciate all of it, and can tell well from poorly executed within those areas. I'm not sure we can force ourselves to like everything, but I'm living proof that we (sample size of one) can force ourselves to recognize quality in every domain.
I would be keen on whisky if it wasn't for the fact that I rarely drink to begin with, and the price is non-negligible.
I started trying out whisky when I realized that for the amount I drink, the price even of fairly expensive whiskies didn't add up to all that much each month.
So you're in the same situation as me, yet arrived at the opposite conclusion, and I think you're probably right. :)
I'll reconsider my stance and will pick up a couple of bottles and dip my toe.
But seriously. My Irish mate started me on it and I really didn’t enjoy it at the start. But he kept buying it for me. And I kept drinking it. And now I love it more than words.
What would you recommend for smoky scotches that don't have much iodine? (Talisker is on my short list right now.)
