Best method to "cook" fresh sausages - Italian, Polish, Bratwurst, etc.

A few days ago I queried the board on the appropriateness of boiling sausages in beer, especially when kids are to be served. The response was generally that it was fine, that the alcohol would evaporate and not cause any problems for youngsters.

I guess the broader question is...do you have favorite cooking methods for fresh sausages? I just picked up some great homemade fresh polish sausage (not smoked) and my typical method to cook this is to boil it for 45 min to an hour. When I make bratwurst or italian sausage, it's usually just grilled outside.

I'd be interested in other's methods to cook the best tasting sausages I can. I've heard just boiling in water cooks them but the flavor escapes and they turn out "too soft" while just grilling chars the outside too much before the sausage is really "done".
