Also, if you're looking at price points, consider how many days in a season you're going to put on them. Some lower end boots will last 30-50 days (or less) while some of the more expensive boots will last 70-100 days (or more) before parts (outsole, laces, etc) start breaking.
In the end, follow _stark's advice. Having a great time sliding on snow starts with some boots that will be comfortable for the entire day.
