You first have to decide what type of riding you'll be doing. That will tell you what kind of quad to get.
For pure recreational riding, a sport quad would be a good bet. If you think you might need to do some work from time to time, you might consider a utility ATV.
If you're buying for the kids to ride, then you definitely need to look at Children's ATVs, or perhaps a Side by Side (UTV) if you plan on taking the kids or other passengers on the same ATV.
