what's similar to Johnnie Walker Blue, but not so expensive?

I am looking for a whisky that is similar to Johnnie Walker Blue, in that it gives a very very smooth warm drink, yet not as expensive. Could you give me two of your best choices that are like that? And cost between $60 to $80 a bottle? I understand that all whiskies are not the same, but from your opinion which two would you say are closest to the BLUE and yet not as expensive? Also, what do you think of Chivas 18, is that very smooth and close to what the BLUE is?
