Al,
whatever mic you buy, if you're home recording...buy the little presonus tube-pre and run it through there first...it is a tube pre-amp that will warm and thicken anyone's vocal on virtually any mic...it's maybe $90 or $100 bucks...hell buy it first, you might not need a new mic...ha...here's a link to it...Moker
