Time to find examples of beer styles.

In preparation for my parents visit in April, I'm going to assemble some of my favorite beers for them to try.  It's easy for me to find some that are very malty, because that's what I like.  I'm going to try and find a good example of several different styles and then have a tasting for my parents.  Just to help me dial in basic examples for people.

Styles I need to find examples of
American Lager or Light Lager - Budweiser ?
German Pilsner - Warsteiner
English Pale Ale or ESB - Bass or Boddingtons
Irish or Scottish Ale - Sun Kings Wee Mac
IPA / APA - Dogfishhead 60 min
Brown Ale - Newcastle
Porter - Sierra Nevada
Sweet Stout - Widmer Snow Plow
Dry Stout - Guiness
Belgian Wit Beer - Hoegaarden

Weigh in with your style / brand preferences

There are several styles I'm missing, but they aren't nearly as common.  I'm looking for a good tasting, easy to find example of each
