Need alchohol suggestions, brother coming home from Iraq

[bottomset]

He has been in Iraq since March 06, was initially scheduled to return at the end of March07, but had his stay extended till July12(followed by 2week debriefing at a US military base). While bad in its own right, ended up being a major beat, as he was going to be the best man in our cousin's wedding July7th and is now unable.

I was looking for alcohol suggestions for the party when he gets back, budget of $650-1000, around 15people that will be drinking

Champagne
is Dom Perignon worth the price?

Nice bottle(s) of scotch as a welcome home gift
I'm pretty clueless when it comes to scotch

Assorted other liquor for drinks
