Welcome to the forums and I'm pleased to hear that you and your fiance both enjoy Talisker. Tasliker and Oban were two of the next SMs that I was able to acquire bottles of, after Glen and his brother by a different mother (Glenlivet and Glenfiddich).
If you enjoy Talisker, I would also propose several of the following Islays: Ardbeg, Caol Ila, Lagavulin, Laphroaig, after which some milder Islays are Bruichladdich, Bowmore and Bunnahabhain.
