I'd have to go for vodka...it's easily mixed if the person doesn't like a strong alcohol flavor and it's not as expensive (at least here) as equal quality whiskies or tequila (I hate rum). I agree with Punk...Stoli is is a good way to go as far as inexpensive vodka is concerned.
If it were *my* 21st...show up with a bottle of Don Eduardo and you'd be a friend for life
