Balvenie 12 double wood is a quality choice in your price point. Balvenie is by far my favorite distillery and their line can take you on a journey. Balvenie 14 Caribbean cask is my best bang for buck scotch. It runs about $55-$60 but drinks like a much more expensive bottle. Auchentoshan is another fine distillery that has a great 12 year old in the $45 price point.
I've got to say that if you've never tried The Yamazaki line of single malts you're really missing out. The 12 year is exquisite. It does run about $80 but worth every penny. The nose is complex and zesty. Taste has some soft citrus bitterness and spice and it finishes nicely with a vanilla sweetness that doesn't over power. I'm by no means a connoisseur and I have a difficult time explaining smells and tastes but this whiskey is just all around pleasant. If you're a big fan of smoky, peaty whiskeys such as Talisker you might find The Yamazaki a bit sweeter but there is a hint of peat in there.
Japanese whiskeys have a shorter finish, I find. But the complexity is amazing given how light they are. I agree with rossi that you must try Yamazaki or even Nikka even just once.
