What scotch is impossible to get in the US? What should I bring home?

Entering my 4th year at a Scottish uni. Each year I bring back a bottle or two, but most have been pretty mainstream stuff.

I probably won't work in the UK after I graduate, so what scotches should I bring home to the US this year? My tastes lean towards less-peaty (Dalwhinnie, etc), but I'm not opposed to bringing home something smokey.
