I believe the KA is a rebadged (and overpriced gaggia). You can do much better.
The answer to your question depends upon your anticipated usage. How many coffees in a session? How many of these are milk based?
Additionally, do you have a decent grinder already? Most people here will suggest that its the most important factor (or at least the most overlooked). Ideally you would spend $300-$800 on one. Looking in the for sale section on this site can find you some good deals.
hope that helps,
