What's your definition of a "bunch of money"? It would be easier for people to make recommendations if they knew what you budget was. To get an idea of what the various guns are going for, check out Bud's Gun Shop, http://www.budsgunshop.com/catalog/index.php/cPath/21
I'd suggest a 9mm as you get, IMO, the most bang for the buck as it's a good SD round and doesn't break the bank at the range. Without knowing what price range you're in, it's hard to make a suggestion as to brand.
